* 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.
* When inlining a page in another one, links from the inlined page are now
expanded the same as they are when rendering the inlined page as a
standalone page. So rather than being expanded from the POV of the
inlining page, they are expanded from the POV of the inlined page.
For example, a link from blog/foo to "bar" will now link to blog/bar
if it exists. Previously this needed to be a link explicitly to
"blog/bar"; such links will also continue to work.
(This was slightly complex to do as the link still has to be constructed
relative to the inlining page.)
* Add a html validity check to the test suite, using the wdg-html-validator,
if available.
* Make the html valid when there is nothing in the actions list by adding an
empty <li> to the end of it.
* Reordered some function call parameters for consistency.
