Better MidiModel command framework, ready to go for all your canvas editing needs.

Browse source 
Rewrote MidiEvent to be a well-behaved self-contained object that optionally owns it's buffer, has proper copying semantics, etc.
Fixed crazy bugs triggered by adding lots of events with varying times to a region.
Speed up initial session display significantly (don't redraw each MIDI region tons of times, though still happens more than once and can use fixing...).
