Azareal ea63768a8e Added a custom auto-link parser rather than using a regex.
Added the Tempra Cursive theme. A fork of Tempra Simple which is less boxy and uses the cursive font.
Improved the theme manager. Primary themes and variant themes (themes based upon another) are now seperate.
plugin_bbcode has been modified to use the URL parsing facilities of the core rather than implementing them itself.
git:// and ftp:// links are now supported by plugin_bbcode.
Added the simple quote BBCode.
Fixed a bug in route_like_topic where the no row error type isn't handled properly.
Moved the rowhead class onto the right element in the topic template.
Removed a couple of linebreaks in the topic template in favour of pure CSS.
Converted some inline CSS in the topic template into new CSS classes.

alerts.png contains some alert types for features which haven't been implemented yet, this is mainly to test if the alert system would work under the presence of those alert types. Think of this as my plans for the future.
