[PD-dev] New object to detect # of channels? (was: Removing [output~]?)

[Alexandre Torres Porres]

ok, here's a (maybe stupid) idea, currently, this object I designed gives
you a channel number of "1" if nothing is connected to an inlet~, not sure
if possible but maybe "sp[0]->s_nchans" could give us "0" if nothing is
connected to an inlet~, so this object could be used to also detect inlet~
connection...
