Add some sample code to retrieve the name of the connected MIDI device

Browse source

	* modules/controller_linux_input.c: Add some sample code to retrieve
	the name of the connected MIDI device (ALSA).
	Do not set the "name" when connected to Alsa, since snd_seq_name()
	returns an uninteresting name.
