while fixing the issue is trivial, i wonder what's the best way to proceed.
simply changing the port-names from "input0" to "input1" will probably 
break all existing auto connection-setups (e.g. qjackctl patchbays).

currently they will do something like:
  "puredata:output1 -> system:capture_0"

if we just renumber the ports, this will *certainly* introduce 
off-by-one errors (e.g. have movie dialoge come out of the sub woofer).

so we probably should name the ports slightly different, so that 
"output0" becomes "output_1".

(the ALSA backend of jack uses underscores as a separator; but Ardour 
(somewhat canonical) uses spaces - though i'd rather avoid that)

what do you think.
