Add some methods to listener, to receive ActiveSensing, Start, SongSelect etc. messages.
(Existing method onMidiSingleByte or onMidiSystemCommonMessage are also called for the compatibility)

MidiOutputDevice

Add methods to send some kinds of message directly; like sendMidiActiveSensing, sendMidiStart, sendMidiSongSelect etc.
They call sendMidiSingleByte or sendMidiSystemCommonMessage methods.
