FunkBox updated

A big update for Funkbox and a promise of a 2.0 too!

• Added preliminary "tweak" menu with new timing options for added funk
• Swing function, 8th or 16th note swing
• Accent function, emphasizes even beats
• Random function, random timing and volume variations
•  NOTE: in this version we are just testing these new features out, they are there to experiment and play with, but the values are not currently saved with a pattern, or saved when you quit, or saved with a MIDI file. They are used with audio export. We will integrate them better in 2.0

This is the last feature update until a bigger 2.0 release, which will be a little ways out.
