cvs updates

The downloads now cancel properly and the banners now display correctly.. In addition, one banner is displayed per 30 seconds not whenever they are downloaded.. So that means that multiple banners won't change every time your download one.

TODO:

Make it so that queued sources don't hold up the entire download.

Make it so that more sources are searched for continuously instead of only once at the begining of the first download.

Changed the colors of the sub-progress bars

Resumable multi-source download, baby!

and misc other cleanup...

Source forge stats are broken again so you can't see CVS updates in the stats.
