Mini issue tracker
Described more fully on [my blog](http://e-scribe.com/news/230), but the gist is: this model becomes a sort of mini-app in your admin, allowing you to record and track issues related to your other applications. Sorting still needs some work. UPDATED 2007-03-14: Fixed repeat in Admin.list_display (thanks, burly!); added Admin.list_filter; changed app list (why did I call that `PROJECTS`, anyway?) to omit "django.*" apps
- admin
