[mythtv] mythbackend options: --setverbose

[Todd Brunhoff]

Not crucial, but a bug nonetheless. In the process of trying to set 
verbose options on the backend, I misread the usage and specified:

mythbackend --setverbose commflag,important

... not realizing that it had to do with a master backend, which I don't 
have. Looking at the main.cpp, it should call ConnectToMasterServer() 
and fail. Instead, it aborts on startup when trying to do something with 
Qt. The log goes like this:
