Rewrite of the AudioStream API

Browse source 
-Fixes long-standing issues regarding to playing a single stream multiple times simultanteously
-Fixes wrong-looping, starting, caching, etc. Issues resulting from bad original design
-Allows more interesting kinds of streams (stream graphs with streams inside streams!) in the future
