- 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
