Yes, ardour stops hydrogen, but does not start it, since

- ardour(0.9beta1) does not send DEFERRED PLAY
- libhydrogen does not call startPlay()

when they are supposed to do so.
But, quite easy hack to get them there. Though, I still had to adjust 
the recorded track in ardour, which is definitely not what I want. But 
wait....

Absolutely cool. It works like a charm. Forget about MMC, MTC.

VIVA JACK! VIVA ARDOUR! VIVA HYDROGEN! VIVA PLANETCCRMA!
