Began work on simplifying the PyQNet API.  Got rid of blocking/non-blocking versions (everything is non-blocking now, though there's a "wait" operation to block until incoming messages are received).  Also simplified the callback-based (server) interface.  Added (optional) zlib compression to the packages and added support for arbitrarily sized messages.

Probably next up would be getting the Pygame event sending version up and then building a default "portal" application for matching up players.  Not really something people should be integrating into their games yet, but it's beginning to shape up a little.
