Tobias Doerffel 3a827f061f Reworked MIDI event handling in InstrumentTrack and renamed MIDI classes
The MIDI event handling in InstrumentTrack was complex and buggy. It has
been simplified now such that processInEvent() tries to handle note on,
note off and key pressure events. The actions taken should result in
equivalent calls to processOutEvent() by NotePlayHandle instances. The
processOutEvent() function sends according MIDI events to the attached
instruments. All unhandled MIDI events are directly forwarded to the
instrument in processInEvent().

It's possible that some corner-cases are not handled yet with the new code
and we have regressions now.

Furthermore renamed midiTime/midiEvent to MidiTime/MidiEvent to match
coding style.

Closes #72.

// TODO:
// - Better voice allocation: long releases get cut short :(
// - .sbi (or similar) file loading into models
// - RT safety = get rid of mutex = make emulator code thread-safe
// - Extras:
// - double release: first release is in effect until noteoff (heard if percussive sound),
// second is switched in just before key bit cleared (is this useful???)
// - Unison: 2,3,4, or 9 voices with configurable spread?
// - Portamento (needs mono mode?)
// - Pre-bend/post-bend in poly mode could use portamento speed?
// - SBI file import?
// - Envelope times in ms for UI: t[0] = 0, t[n] = ( 1<<n ) * X, X = 0.11597 for A, 0.6311 for D/R
