MPE broken on OSX #22

Can't run MPE sketches where processes ssh to localhost on OSX. Debug output when running MPEPeasy.pde with configuration_localhost.xml:

Tested this today -- replicated issue by running ssh localhost, setting the DISPLAY variable, and launching a simple Processing sketch. Also fails when doing the same from a remote host:

java.awt.HeadlessException: No X11 DISPLAY variable was set, but this program performed an operation which requires it.

NOTE: determine the proper DISPLAY variable setting on OSX by launching terminal window in XQuartz and type echo $DISPLAY
