Raspberry coud play music too

I implemented your code to Raspberry Pi. I let in the arduino code too, reorganize the code a bit. The graphical interface get very pure modifications. Some minor bug coud be there, but i think its working. (I cant try it with multiple floppies and after the code integration, but it worked separately.) It's use udp instead of serial. In the future the tcp coud be more effective.

I will see whats modified in the advanced, and I make an another request to there if you like this idea.
