restore rec-enable, solo & mute functionality; remove all Global*Command cruft; reimplement momentary solo&mute; refactor session RT event stuff to be even cleaner and finally compatible with everything-is-a-UI idea ; make all UIs derive from a primitive type that pprovides only void call_slot (sigc::slot<void>) as a way to execute arbitrary code in the UI thread
