OSD callsign suport #122

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
OSD should support displaying of call-sign (arbitrary text), this is to comply 
with legal requirement of transmitting call-sign with (video downlink) radio 
signal. 

I will attach the necessary bits here after making the patch a little more 
generic.
