Ensure that tuning obeys the command-line parameter rather than
hard-coded value in tune.c 

In tune.c, the QAM tuning parameter INVERSION_OFF
causes tuning to fail (Cinergy 1200 DVB-C budget card,
linux 2.6.12, HTV cable network in Finland). 

Patch from patch tracker in Sourceforge. thanks to anonymous.
