[output] Ignore empty commands

Browse source 
When receiving a "nop" (None) command, skip it. Otherwise, an exception
is thrown and input processing stops.

Also, remove the "communicate()" call to *not* wait until a process has
finished until resuming input processing. Otherwise, whenever an
external program (pavucontrol, nautilius, ...) is started, any further
input processing is stalled until the program has been closed again.
