[PD] jack_transport improvements

[Jacob Lee]

What are you using as the jack transport master? This external doesn't
have the capability to act as the master, so something else has to set
the tempo and time signature (that's what I'm using klick for). And pd
has to be computing audio, since the plugin gets the current transport
position during the pd dsp cycle. Those are the two things I would
check. (I don't think jackd prints anything in this case, by the way.)
