Merge pull request #1 from RJacksonm1/master

Some template and admin changes
Started working on the topic tracker

I couldn't finish it because I'm a bit busy.. but feel free to work on it :)
The topictracker is working now. But I still need to implement the `untrack` functionality.
Finished the topictracker
Minor fixes

Check load_user's query has results before attempting to unpack - fixes an edge-case exception where the visitor has session cookeis for a user that no longer exists in database.
Changed new post, new topic, and quickreply forms to use the macro form render functions - thereby displaying validation errors for those forms.
