Fix some workflow problems wrt automation.
- clearing automation points sets control to "off" rather than touch.
- multiple touches on the same pass acts consistently (no more
fader jumps on mouse button press
- use actual value for initial point rather than some arbitrary
default. clarify new semantics of add () (with_default->with_initial).
- clean some whitespace
- add guard points as needed in stop.
- catch grab broken signal (i can't trigger it, but the docs seem
to think it is essential).
