track naming patch from brian; slightly modified F11-bug workaround from brian; undo/redo items in edit menu now show operation to be undone/redone; canvas allocations now handled by an idle handler; region views respond to changes in fade/in/out curves ; undo/redo possible for some fade in/out operations; automation tracks extend to max_frames
