UDP Fixes

-=-=-=-=-

Curse the day I decided to port UDP code, as it ended up
being two nights of work.  At least It's done now (I hope).

-Fixed UDP Support, API seems stable
-Added UDP Chat demo (chat that can lose your packets, heh)
-Added helpers to areas and bodies to get list of collided bodies and contained bodies.
-Sped up screen/viewport capture code.
-Added code to save an image as PNG
-Small fix so scripts register their singletons after modules did.
