Prepare for Syncing hell

1] Added musicPlayer class. Allows for playing of music/sounds
2] Added menu class. It loads the main menu
3] Added button class. Buttons interact with mouse input and you can add
your own buttons with this class (better than JButton, umpf)
4] A few wav files were added to test sound playing
5] LOTS of unnecessary classes (bc testing/struggles)
6] LOTS of pictures (bc why not)
7] Added Window class - it is in charge of managing window size,
resolution, etc.
