Rainbow Fury! Colorful death!

Rainbow Fury is a passive item that appears in angel rooms, boss rush, or dungeons. For every tear you fire, it changes color according to the rainbow and increases your stats while it's at it (as shown in the images above). It synergizes with many items, and if you find an item that it doesn't synergize with, tell me in the comments below. Also, report any other bugs that you find, as that'd be greatly appreciated.

I will constantly update the mod to fix bugs that both you guys and I encounter.
