Close MIDI Player to prevent memory leak

public void deallocate() { state = Player.CLOSED; }

Hello Hex007!
I think calling MidiSequencer.close() when deallocating a player which is an instance of a MIDI player can help prevent memory leak. (There is a particular game that re-creates a MIDI player every time when the character enters a new scene, so after entering 100 scenes or so the program starts to consume ~600 MB of memory and have ~200 running threads.)

On Linux, having more than a few MIDI players will cause the music to stop, but this doesn't happen on Windows.

The fix may look like the following:

public void deallocate() {
	stop();
	if (player instanceof midiPlayer) {
		((midiPlayer)player).midi.close();
	}
	player = null;
	state = Player.CLOSED;
}

Thanks!

p.s. A similar issue and the usage of close() is mentioned in this Stackoverflow post: Java Sequencer using all memory? (7kb midi file)
