Splitscreen sound support

[GoogleCodeExporter]

Need to support multiple listeners in the base and OpenAL sound systems. Sounds 
should play relative to all players.

Added framework for multiple listeners. OpenAL just ignores splitscreen sounds. 
Base sound, while it does play splitscreen sounds, could be better.

Thoughts; Is it possible to have the OpenAL Listener at 0,0,0 and put sound 
points relative to my listener points?

Not only OpenAL ignores splitscreen sounds. SDL sound also has problems with 
splitscreen sounds (e.g. only one splitscreen client can hear his own jumppad 
bounce sound, mainly splitscreen client > #1)
