Java and Midi Volume

Good news:
Got the Options Panel in.
Got the Midi choice toggle in.
Got a Play Midi button for checking whether they want it on Option Screen.
Added a Save configuration button.
Configuration checks whether sh.cfg exists, deletes it if it does, and writes a new she.cfg file.
LoadConfig() added to PlayButton to load PlayMidi Boolean.

Bad news:
Java volume controls of Midi using sliders is a bear. Will come back to it.
