This reverts commit 278e3f27f8c15ee96103164d95114a82121bfaeb.
Added sound files and the ability to play them

Added sound files to the project. Created MusicNote objects for each
sound file. Changed the audio player for the MusicNote from SoundPlayer
to a Windows api call because SoundPlayer would only allow one audio
file to output at a time.
Added the ability to play Piano notes by either pressing the piano
buttons or pressing the mapped keyboard keys
