[mythtv] Live TV override

[Steve Hill]

I'm not a C++ coder (I use C normally) so this is probably not the best 
bit of code.

This is a hack allow you to set a rank to apply to LiveTV (set up in the 
rankings settings).  Recordings below that rank will be automatically 
cancelled if you are watching live TV.  I.e.  you can set Myth to record 
every episode of The Simpsons but not when you're already watching 
something else.

Comments would be appreciated.

At the moment this only looks at the program rank, not the channel and 
recording type ranks (what's the best way of actually finding the total 
rank for a program?).  Programs that will be overridden by LiveTV will 
appear red in the conflicts screen (I've patched the Visor theme so far.  
I haven't gotten around to patching the Blue theme)
