Sound Timing

I implemented a sound timing class tonight, and tested it out by creating a simple speaker looking object in GIMP and having it pulse at 120 beats per minute. I wrote a Speaker class that extends Sprite to take care of the graphical side of things. The sound timing class should be pretty robust and should help us with things from graphical pulsing to note timing detection.

I'm hoping this leads us in the right direction to start implementing gameplay. I asked Ada to work on a state pattern so we can have different states like the menu, rails mode, battle mode, etc. So maybe I'll start working on the battle mode stuff next now that I have a better idea of timing.
