* The last release accidentially installed ikiwiki as ikiwiki.pl, now fixed.
* Add --version.
* Man page format fixups.
* Add a %pagecase which maps lower-case page names to the actual case
  used in the filename. Use this in bestlinks calculation instead of
  forcing the link to lowercase.
* Also use %pagecase in various other places that want to check if a page
  with a given name exists.
* This means that links to pages with mixed case names will now work,
  even if the link is in some other case mixture, and mixed case pages
  should be fully supported throughout ikiwiki.
* Recommend rebuilding wikis on upgrade to this version.
