David Robillard 60454cc8dc Split pretty much the entire GUI in 3. Audio and Midi "editor strips" and
associated stuff are now separated (with common things in base classes).

Extremely dirty and in progress, but builds, runs, and audio/midi tracks/busses
all look (and really are) distinct in the GUI.
