Links to non-existent pages now show up in red
Uploading other file types has been unlocked
Previews for videos / audio files and PDFs have been added
A nasty bug in the parsing of internal links has been fixed

Extra changes made since v0.11-beta2

Redirect to audio / video in preview generator if the data storage directory is the current directory

Unlocked the uploading of any file type. Note that only the file types specified in the settings are allowed to be uploaded.
- Uploaded video and audio files can now be viewed on their respective pages
- The file preview tool is now aware that not everything will be an image.
Enhanced the recent changes page.
- New pages show up with an 'N' next to them (as they do in a MediaWiki installation)
- Page deletions show up in red with a line though them
- Uploads show with an arrow next to them along with the size of the uploaded file
Added mathematical expression parsing between dollar signs.
Generated previews now have etags. This should speed up load times of subsequent requests significantly.
Added some extra built-in variables to the parser.
- {{{~}}}: Displays the top level page name (i.e. the page that has been requested).
- {{{*}}}: Displays a comma-separated list of subpages of the requested page.
Links to non-existent pages are now coloured red by default.

Enhanced the dev help page some more
Changed the uploaded file preview generation to use imagemagick. You now need to have the imagick php extension installed (installation on linux: sudo apt-get install php-imagick).
The uploaded file preview generation action will now return audio and video files as-is. This allows for HTML5 video / audio tags to be used to view audio and video files.
Made username box autofocus on login page.
Added tab indexes to editing form

Conflict resolution. If someone saves an edit to a page after you started editing, you will get a conflict resolution page.
