Experimental automation recording support

Allows you to record automation by arming an automatable model
and then recording with the RecordAndPlay button.

Known bugs:
	* when you record and there is already an auto clip, it repeats it
	* it freezes when you try to do it with the Volume or Panning slider
	* crashes when you try to do it with a solo/mute button
