Update to 3.20110707. From the changelog:

* userlist: New plugin, lets admins see a list of users and their info.
* aggregate: Improve checking for too long aggregated filenames.
* Updated to jQuery 1.6.1.
* attachment: Speed up multiple file uploads by storing uploaded files
  in a staging area until the page is saved/previewed, rather than
  refreshing the site after each upload.
  (Sponsored by The TOVA Company.)
* attachment: Files can be dragged into the edit page to upload them.
  Multiple file batch upload support. Upload progress bars.
  AJAX special effects. Impemented using the jQuery-File-Upload widget.
  (If you don't have javascript don't worry, I kept that working too.)
  (Sponsored by The TOVA Company.)
* Add libtext-multimarkdown-perl to Suggests. Closes: #630705
* headinganchors: Plugin by Paul Wise that adds ids to <hn> headings.
* html5 is not experimental anymore. But not the default either, quite yet.
* Support svg as a inlinable image type; svg images can be included on a
  page by simply linking to them, or by using the img directive.
  Note that sanitizing svg files is still not addressed.
* img: Generate png format thumbnails for svg images.
* Preserve mixed case in page creation links, and when creating a page
  whose title is mixed case, allow selecting between the mixed case and
  all lower-case names.
* Fix ikiwiki-update-wikilist -r to actually work.
* comments: collect metadata in a scan-phase preprocess hook, which
  fixes sorting comments by date. (smcv)
* Run scan hooks for internal pages (preprocess hooks already run in scan
  mode) (smcv)
* inline: Handle obfuscated urls, such as the mailto urls generated by
  markdown when forcing urls absolute.
* Bugfix for wikilink containing an email address not showing up in
  brokenlinks list.
* Bugfix for trying to attach files to a subpage of the index page.

Updating this leaf package during the freeze for bugfix purposes.
