Changes
- Users can now upload torrents as anonymous
- Recoded the plugins. Now we have "System - Tracker" and "User - Tracker"
- Recoded the user listing and edit screens - Added the donated amount and credited bytes
The component can be downloaded from the websvn, in the usual place.
Any new bugs are welcome, I'm trying to make this as stable as possible to give it a real test.
