Merged with master
Pause and Play work still need to make it so m pauses and restarts music
pause/play music
pause and play works correctly now.  I had to change the way we handle key presses a little since the pause needs to only detect one key press in order to work propperly.  We now check to make sure a key press is in the list before we remove it.
cleaned up the Music class a little bit
Sound doesn't work
???
testclass is now a class and it is starting to come together
