Things with automation parameters now inherit from Automatable, which handles serialization, fetching/adding/removing parameters, etc. Use AutomationList everywhere instead of Curve, make Curve a member of AutomationList instead (towards other types of "Curve" needed for CC, among other things). Work towards MIDI CC sending "automation" tracks. git-svn-id: svn://localhost/ardour2/trunk@2069 d708f5d6-7413-0410-9779-e7cbd77b26cf
