diff main/MainWindow.cpp @ 217:69f83e36b8e5

* Add Erase tool and mode
* Add icons for Normalize buttons in property boxes, and for Show Peaks
* Add support for velocity in notes -- not yet reflected in display or
  editable in the note edit dialog, but they are imported from MIDI,
  played, and exported
* Begin work on making pastes align pasted times (subtler than I thought)
