Scheduler rearrange logic could be more optimized about sagetv

So this would require checking if more than one tuner offers that airing, and if so, try a different one for that airing, and recheck the conflicts? There's have to be a way to track which of the available tuners have been checked with this file in this iteration... Might be.. messy.

Yeah, this is far from an easy change to do...it was just on my list of things to fix that's been sitting there for years so figured I'd add it to the tracker. :)
