[mythtv] Proposed patch to mythfrontend/main.cpp

[Jim Brunner]

I wanted temperature info on the status screen (my TiVo does this).  
This patch to mythfrontend/main.cpp will check for the existence of 
mbmon.  If available, it is run and the 1st two temperatures are 
assumed to be the case temperature and CPU temperature respectively.  
This works great on my machine but may not work the same way with other 
motherboards.  (I'm not really sure if this is a problem or not.)

This patch should have no impact if mbmon doesn't exist.

It would also be handy to have the status screen indicate if the 
backend was up (and possibly its status [recording, idle, etc.])  But I 
haven't tried to figure that out.
