available templates. Rename the old templates page to wikitemplates.
* Include the note template in the basewiki.
* Add a popup template in the basewiki. CSS based on some by Martin Krafft.
* Make the note, popup, and plugin templates detect missing variables and be
self-documenting, listing the available variables.
* 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.
