Added sound functionality

Sample playback!!
- Changed the layout to not use the fullscreen one cause that seems
glitchy and ugly.
- Implemented the SoundPlayer class which will play all of your sounds
for you.

TO DO:
- Josh, all of your new classes are in their own packages, haha. I'll
move them into one package later.
- Rigorously enforce coding style, haha.
- Make the record button do stuff.
