[mythtv] [mythtv-commits] Ticket #4013: Prompt before upgrading database schema

I'm not sure about the 'Use old schema' option - that's too likely to corrupt 
things, I'd think.

Actually, it might make more sense to just pop up a message and say 'Please 
run mythtv-setup on the master backend to upgrade the schema', and refuse to 
run until that's done.
