* Add command history class, and basic undo/redo menus. No actual commands
to undo/redo yet. Selecting the placeholders sometimes seems to cause
a crash, so this looks a little uncertain so far.
* Add Rename Layer
* Remove models from playback when their layers are removed (and ref counts
hit zero)
* Don't hang around waiting so much when there's work to be done in the audio
buffer fill thread
* Put more sensible names on layers generated from transforms
* Add basic editing to time-value layer like existing editing in time-instants
layer, and make both of them snap to the appropriate resolution during drag
