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 :-)

backgrounds. A test file was added to lib/images/fileicons/index.php

Uses the first heading as the page name in the default template
if $conf['useheading'] is set. Updates tpl_pagetitle() so that it
can return this value.

- 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 !

Tells standards compliant browsers that conditional requests for
CSS and JS need only be made once an hour. This should reduce page
display latency on some browsers.

This patch updates the feedcreator.class.php with a few non official changes
found at [1] - the download link didn't work at this page so [2] was used.
Some additional minor modifications were done.

feed.php now accepts the type

- Using the export modes 'handler', 'lexer', 'parser', or 'renderer'
  now produces a nicer non-fatal error.
- The export mode 'wiki' is now ignored to avoid fatal errors.

This patch rewrites export urls so that robots.txt can be used
to request that some (or all) export types are ignored by
robots when indexing the wiki.

For example:
User-agent: *
Disallow: _export/

or for example:
User-agent: *
Disallow: _export/raw/

Note: This rewriting is only done when $conf['userewrite'] is
set to '1' for using the rewrite rules from '.htaccess.dist'.

The old pattern (left as a comment) allowed many PHP syntax errors
to be inserted into local.php for numeric values. This was breaking
the wiki... see bug #769.

This patch should eliminate the syntax errors by using a more restrictive
definition of numeric settings.

  - The RSS feed now handles conditional requests and returns HTTP '304 Not Modified'
    responses when possible.
