Applied patches supplied by Andre' Breiler:

- bugfixes for display != MatrixOrb LCD
	- changes the meaning of output_state
		+ it's now a bitfield where evry bit corresponds to
		  one output
	- protocol change
		output on|off|value
		where on    = all outputs on
		      off   = all outputs off
		      value = output on for all 1 bits
	- changes the behavior for key presses
	  Keypresses are now deliverd to _all_ clients (not only
	  the one with the active screen)
	reason: I have an client which is only active a few seconds after
                an keypress
	- changes the protocol so that a response is sent for every
	  command
	reason: the client needs to communicate with the server with a
                minimal latency
