* Added plugin system, currently only supporting for PreProcessorDirectives.

* Added a pagecount plugin, enabled by default.
* Support PreProcessorDirectives with no parameters, ie "[[pagecount ]]".
* Fixed/optimised backlinks code, to avoid rebuilding pages to update
  backlinks when the backlinks hadn't really changed.
* Moved inline page support, rss generation etc into the inline plugin,
  enabled by default.
* Added brokenlinks plugin, not enabled by default, but rather handy.
* Fix several broken links in the doc wiki.

-  Could be implemented with a [[preprocessordirective]], which suggests that there needs to be some sort of plugin interface for new preprocessordirectives. Although, how to let the wiki know that the page needs an update whever a new user is added?

 ## preprocessor plugins
 
-Considering ikiwiki plugins, one idea I have is to make the [[PreProcessorDirective]]s be a plugin. A setting in the config file would enable various plusins, which are perl modules, that each provide one or more preprocessor directives. 
-
-Since preprocessing happens before htmlization but after a page is loaded and linkified, it should be possible to use it to create something like a link map or lists, or a page index. Page inlining and rss generation is already done via preprocessor directives and seems a natureal as a plugin too. 
-
-Note that things like a link map or a broken link list page would need to
-be updated whenever a set (or all) pages change; the %depends hash
-already allows for pages to register this, although there could be some
-strange behavior if mixing multiple directives some of which exclude pages
-that others might want to include.
-
-I need to look at the full range of things that other wikis use their plugin systems for, but preprocessor directives as plugins certianly seems useful, even if it's  not a complete solution.
