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 git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/trunk@504 b956fd51-792f-4845-bead-9b4dfca2ff2c
