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. git-svn-id: svn://localhost/ardour2/trunk@2080 d708f5d6-7413-0410-9779-e7cbd77b26cf
