Added an AI enemy class and turn based functionality.
Added Object Orientation for AI Behavior

Audio - Initial commit

This is the initial commit of the audio branch.

**KNOWN BUGS**
- If playing the loopTest.wav clip looped, after the first loop the
"pause" function no longer works correctly. Instead the clip resets and
plays from the beginning again.

This is the final audio for the audio branch. After this branch, audio
should be merged into the Master branch for use within the engine
Audio Reformat

Reformatted audio so it works within the BlockGame1 engine instead of a
seperate class
