* Reformat calendar plugin to ikiwiki conventions.
* The calendar plugin made *every* page depend on every other page,
which seemed a wee tiny little bit overkill. Fixed the dependency
calculations (I hope.)
* Removed manual ctime statting code, and just have the calendar plugin use
%pagectime.
patches can now be anywhere and tagged patch to show up on the patch list.
Moved all the patchqueue stuff to todo items; some of it was merged into
existing todo items.
