proof of concept implementation of static recentchanges

Currently hardcoded to write to recentchanges/*, and the page format needs
to be rethought to be usable for aggregation, but it basically works.

+
+This plugin examines the [[revision_control_system|rcs]] history and
+generates a page describing each recent change made to the wiki. These
+pages can be joined together with [[inline]] to generate the
+[[RecentChanges]] page.
+
+Typically only the RecentChanges page will use the plugin, but you can
+use it elsewhere too if you like. It's used like this:
+
+	\[[recentchanges pages="*" num=100 template=change]]
+
+The pages describing recent changes will be created as [[subpages|subpage]]
+of the page where the `recentchanges` directive is placed.

   aggregator, or they can set up their own page that uses the recentchanges
   directive for only the pages they want.
 * The `rcs_notify` functions will be removed.
-* `rcs_getchange` is passed a change id (as returned from rcs_recentchanges)
-  and a partially filled out HTML::Template and fills out the remainer of the
-  template. So if a template is used that includes diffs, it will need to run
-  some expensive diffing operation, wikis with less resources can use a
-  template that doesn't include diffs and avoid that overhead.
+* To add diffs, another plugin can add a pagetemplate hook that calls
+  a `rcs_diff`. (optional)
 * So to update the changes files, just call `rcs_recentchanges`, create
   files for each new id, and delete files for each id that is no longer
   included.
