Video backend selection

[Jesper K. Pedersen]

I don't feel strong either way.

The dialog is a one time dialog that shows up as you upgrade KDV, and 
given the trouble that all three plugins have I think the user should 
know what he chooses otherwise he will just end up wondering why the 
preview doesn't work all of a sudden (if you switch from QtAV to one of 
the other backends behind his back).

But again, I don't feel strong about it. Maybe at least inform him that 
you are switching backend when doing so, and offer him the config dialog

Cheers
Jesper.
