Paul Davis 1c49138e00 move MidiPortManager from AudioEngine to Session
This makes the responsibilities and ownership of non-Route related MIDI ports
more clear, and removes a few wierd bits of code. It also ensures that open/close/open
on the same session will retain connections for those MIDI ports
