David Robillard 24ccaac67e Further automation refactoring - bring in the concept of Controllable, work towards
making automation + GUI + play/write/touch generic and easily reusable.
Added bar controller to automation track controls (mostly relevant for MIDI CC, but added for gain and pan too Just Because).
Fixed glaring "redirect" list errors.
Fix plugin controls/automation loading.
