This fixes a typo which made the new Feedparser not use our own HTTPClient.
It also enhances the get() method of HTTPClient to optionally cope better
with bad HTTP responses:

Some servers return a body with a "304 Not Modified" status which violates
RFC 2616 but is usually accepted by common browsers. Setting the $sloppy304
parameter will return the response body. This fixes problems with feeds
from feedblendr.com

The HTTP Cache-Control header output now respects the Dokuwiki media parameters
'cache', 'recache', and 'nocache'.
  - cache: cachetime or one hour (which ever is larger)
  - recache: remaining cachetime + 10 seconds so the newly recached media is used
  - nocache: no caching

Notes:
  - 'proxy-revalidate' should ensure that public caches always revalidate, this
    will keep caches from (accidentally) ignoring Dokuwiki's ACL rules.
  - 'no-transform' should keep media from being modified in transit by caches.

Impact:
Speeds up page layout/display by browsers when they already have the media
in their [memory] cache. For example the 2nd time a page is viewed. This
also reduces server load by eliminating most of the overhead needed to
return '304 Not Modified' responses each time an image is viewed.

Fixes a major bug in fetching remote media with 'recache' and improves
the efficiency of 'nocache'.

Recache:
  - Used to reload the remote media on EVERY request.
  - Now it behaves as intended and only reloads the remote media
    into the Dokuwiki cache every $conf['cachetime'] time.

Nocache:
  - No longer stores remote media in the Dokuwiki cache.
  - No longer loads, saves, and forwards remote media -- just redirects.
  - No longer resizes images on the server because the cached results
    can not be reused.
Overall this is faster for Dokuwiki. The bandwidth usage for
the 3rd party server is the same (less for Dokuwiki). Page loading
should also be faster because data is not being forwarded through
Dokuwiki (and the 3rd part server's cache control headers will be
respected automatically).

Does client-side rewriting of accesskey tooltip text so that it will be

This is a major revision of DokuWiki's event system.  There are changes to class names,
function names, function parameters and their order and event names.

For action plugin writers the following changes are important:

- <event_name> is no longer signalled, only <event_name>_BEFORE and <event_name>_AFTER.
- note the case change for _BEFORE and _AFTER
- calling stopPropagation while processing a _BEFORE signal no longer prevents an
  _AFTER signal. The events _continue value is reset before the _AFTER signal is made.
- events have a new readonly property, canPreventDefault. This lets the event handling
  hook know whether or not the event honours preventDefault calls.

- parameters have changed for the register_hook method, parameters are now
  $event_name,
  $advise (can be 'BEFORE' or 'AFTER')
  $object
  $method
  $param  (this parameter is now optional)
- parameter order has changed for the hook event handler callback functions
  &$event
  $param  (can now be left off)

Event names have changed, they are now structured
  <dokuwiki name>_<event data name>_<action_name or state if no action>

event   TPL_ACTION_HTML
data    $ACT
action  tpl_content_core (formerly tpl_content)

This event is a wrapper for tpl_content() (now tpl_content_core()) and as such is a
full trigger, meaning it issues three advises:
- TPL_ACTION_HTML_before
- TPL_ACTION_HTML
- TPL_ACTION_HTML_after

Event handlers can output HTML before and/or after the main Dokuwiki page output and
can prevent the default dokuwiki page generation taking place.

Example uses could include:
- replacements for dokuwiki command handlers like index.
- appending a discussion section to the page by handling TPL_ACTION_HTML_after

event   TPL_DISPLAY_HTML
data    html output produced by tpl_content_core[1]
action  send output to browser

Event handlers can post process the HTML output before it is sent to the client
browser. This is a full trigger, meaning it issues three advises
- TPL_DISPLAY_HTML_before
- TPL_DISPLAY_HTML
- TPL_DISPLAY_HTML_after

darcs-hash:20060415160847-9b6ab-d7affcb1aaf49aecfaf9bc1e78a82ceb8ae409f7.gz

Event data an array of headers dokuwiki will send[1].
The default action is to output all the headers in order using the header() function.

This event is a full trigger, meaning there are three advises:
- SEND_HEADERS_before
- SEND_HEADERS
- SEND_HEADERS_after

Handlers of this event can add/modify/delete the headers in the event data. The event
data must remain an array, even if emptied.

[1] There is one dokuwiki header 'Content-Type: text/html; charset

event DOKUWIKI_START

This event is advisory only.
There is no event data
There is no default action

The event is signalled after Dokuwiki has completed its initialisation phase and
before it closes the session.  Most Dokuwiki globals will have been created and
populated, the global $_SESSION var will still be in existence.

Note: Even after $_SESSION has been closed a plugin can reopen the session to
access session data - as long as headers have not already been sent.  For more
information refer to lib/plugins/config/admin.php.

event DOKUWIKI_END

This event is advisory only.
There is no event data
There is no default action

The event is signalled after all processing has been completed as the last thing
doku.php does before exiting. It is possible that under certain circumstances
dokuwiki will exit without returning to doku.php and this event may not then be
signalled.

This event is advisory only.
Event data is the $ACT variable
The default action is to display an "unknown action" message

The event is triggered by tpl_content if it does not recognise the $ACT value. It is
the complement to event 'ACTION_DISPATCH'.  Handlers of this event can output XHTML
which will be displayed in the main dokuwiki window - ie. where the wiki page would
normally be displayed.

darcs-hash:20060414201705-9b6ab-f8ede6a2fb601d734c115ee09bb57195ad7d1e2b.gz

This event is advisory only.
Event data is the handler object.
There is no default action to prevent.

The event is signalled by the handler during its finalisation of the instruction list.
At the time of signalling the instruction list is complete except for three instrucitons,
meta, document_start & document_end.

Syntax plugins could register for this event to finalise processing of their data knowing
it is complete, e.g. an alternate footnote plugin.

darcs-hash:20060414201101-9b6ab-eba2d096ed3b82e1ec6b24ee90caaa9849f16093.gz

The 'ACTION_DISPATCH' event[1] is triggered prior to any processing of the $ACT
variable[2]. This gives custom content the opportunity to add new "do" commands
and to process any custom form data.

This event is advisory only (there are no '_before' or '_after' advise)

Preventing default action will skip Dokuwiki's own processing of the $ACT value, this
includes its cleansing of the $ACT variable.

[1] also refer ACTION_TEMPLATE event
[2] $ACT is the do variable from the query string

darcs-hash:20060414195601-9b6ab-8ae62d2c3a7c6f8c09c77436d9adbaba5404f51b.gz

This patch adds events and a third plugin type, "action" plugins, to DokuWiki.

The patch doesn't include any event signalling, that will be added in later patches.

Action plugins are loaded before most Dokuwiki processing takes place and at the
same time are given the opportunity to register handlers (or hooks) to receive
specific dokuwiki events.

Other parts of Dokuwiki (e.g. templates and syntax plugins) can also register
handlers to receive events.

Any part of Dokuwiki can create and signal events, including templates and plugins.

This patch also revises the admin plugin class by making it an extension of a
new class, DokuWiki_Plugin. The DokuWiki_Plugin_Action class also extends this
new class.

Further details of events, their signalling and handling, and of action plugins will
be added to wiki.splitbrain.org in due course :-)

- revisions to header class and section handling
  header pattern simplified
  header class now writes section open and close instructions
  section call writer removed
  check for and update meta['first_header'] if required (see below)

- meta instruction added
  written by _finalize to front of instruction stack
  holds first header information

  plugins can now write first header information, or other page meta information
  to this data structure.

- get_first_heading updated to make use of meta['first_header']

- plugin instruction structure changed to include lexer state in the data portion
  of the instruction.
  OLD INSTRUCTION:  array('plugin', array(<plugin name>,<plugin_data>,$pos), $pos)
  NEW INSTRUCTION:  array('plugin', array(<plugin name>,<plugin_data>,$state), $pos)

- block handler/call writer update to better handle plugin PTypes 'block' & 'stack'.
  Lexer states are mapped as follows:
    DOKU_LEXER_ENTER, DOKU_LEXER_SPECIAL     : block_open, stack_open
    DOKU_LEXER_EXIT, DOKU_LEXER_SPECIAL      : block_close, stack_close
    DOKU_LEXER_MATCHED, DOKU_LEXER_UNMATCHED : plugin must handle <p>

  Plugin writers can now use these PTypes as intended !
