Pitchbend and Modwheel support

[EthanSK]

Would be cool to support pitchbend and modwheel. just a simple bar that shows the value.

Agreed—there's a lot of cool stuff that could be added to MidiKeys for sure. But lately it's mostly up to other users to contribute changes, since I don't use it myself much these days and have other projects that consume all my time.

That just shows how old most of the MidiKeys code is…
