[Pianod] r232 gstreamer

[Bruce M. Sheplan via Pianod]

I got gstreamer installed (I had to upgrade to debian testing since
gstreamermm was not available in jessie) and I was able to get pianod2
compiled with gstreamer as the engine.  So far so good, only issue is I
cannot figure out the syntax for the room reconfigure command.

With the prior version I was using (respectively for each room):
ROOM RECONFIGURE DEVICE hw:0
ROOM RECONFIGURE DEVICE hw:1
ROOM RECONFIGURE DEVICE hw:2

I've tried the following and none seem to work:

ROOM RECONFIGURE DEVICE "alsasink device='hw:1'"
ROOM RECONFIGURE DEVICE "alsasink device=hw:1"
ROOM RECONFIGURE DEVICE "device='hw:1'"
ROOM RECONFIGURE DEVICE "hw:1"

Any suggestions?

Thanks!
