Heavy-duty abstraction work to split type-specific classes into
specializations of (new, for the most part) generic bases. (eg. most everything
from the MIDI branch except for actual MIDI things, so merges have a chance of
succeeding). Also the new edit toolbar, and various other cleanup things I did
along the way.
Should be functionally equivalent (except the toolbar), this is just design work.
She's a big'un....
