- Removed deprecated line from .ui files - Clarified audio format plugins text - Changed GUI signals to QAction::triggered() (activated() doesn't exist and was breaking the menus on Qt 4.7 on Windows.) - Removed the MIDI sendInhibit stuff, fixing bug #676086. (If we have deadlocks on shutdown, it's because we have too many mutexes. We never realized the wrong threads were calling the MIDI functions and used mutexes when we should've used signals/slots. This needs to be cleaned up for v1.10.)
