We had a lot of options lumped together under "Advanced Settings". I
introduced two more categories and move a few options to other existing
categories.
I also reordered the appropriate entries in the source files to make it
easier to find stuff when extending the options.

Templates authors should support these to make the transition between templates easier. Templates which already have a sidebar could first check for $conf['sidebar'] and use it if it's defined, otherwise use their old own sidebar functionality to stay backwards-compatible.

Translators need to add another string.

renamed plugins.protected.php to plugins.required.php and added it cascade to allow overwriting as a local protected file

Function get_plugin_components() moved to extantion manager

The feature is now disabled by default.
Metadata for config manager was added.

This patch adds a new config option 'cssdatauri'. When enabled, the CSS
patcher will automatically convert all occurances of small (<600 byte)
PNG and GIF images in the CSS to embedded, base64 encoded data uris.

This reduces the number of needed HTTP requests and avoids the HTTP header
overhead.

Before this patch with a .htaccess file on a higher level in the
hierarchy with "Satisfy Any" it has been possible that the directory
protection didn't work as expected.

  * Do not emit E_NOTICEs
  * Introduce explicit feed mode default value »recent« instead of handling
    every unknown feed mode as recent changes mode. This means:
    - FEED_MODE_UNKNOWN is only executed if the given feed mode is indeed
      unknown. This is specifically not the case if no feed mode request param
      has been specified or the requested feed mode is »recent«.
    - FEED_MODE_UNKNOWN dies with an error as default behaviour
  * opt[items] is forced to be a non-negative integer
  * opt[show_minor] is forced to be a boolean and thus has a default value of
    false instead of null

* attention: incompatible to previous version!
* introduced _tpl_action() (wrapper similar to tpl_action())
* improved discussion and user page functions
  * made them work independent from config
  * added full control to how the page links are built (with placeholders @ID@ and @USER@)
* config option changes: removed 'discussNSreverse', renamed 'discussionNS' and 'userNS' to 'discussionPage' and 'userPage'

An external tokenizer inserts extra spaces to mark words in the input text.
