Added IAudioPlayback Interface and implementation for BASS.

Created "AudioPlayback" Global Singleton, which removed the need 
for the "Music" Global variable.  This was done because global singleton objects are 
a recognized better "design pattern" achieving the same thing as global variables, but
in a nicer way.

I will be working to 
  a) separate IAudioPlayback in to separate "Playback" and "Input" Interfaces
  b) build a FFMpeg class that implements IAudioPlayback

-Sorry guys... this is my mess :(
-Im going to try and get ffmpeg to handle audio playback ( at least for linux )
-and Im going to implement it nicly along side BASS, in TMusic ( where I can )
