Video backend selection

[Johannes Zarl-Zierl]

I've now merged the changes as described:

- A video backend is chosen automatically if none is configured yet.
- If a crash was detected during video feedback (you can emulate this by 
killing KPA when a video is shown), a dialog is displayed when a video is 
displayed for the next time. The user can accept or dismiss the change to the 
new video backend.
- If every available video backend failed at least once, a message is shown 
that informs the user that KPA has given up and will not try to change 
backends during future crashes.

If you have feedback, please reply ;-)

On a related note, I want to do a release soonish (second half of May?) to get 
the accumulated bug fixes out and be open to introduce additional features 
again.

Cheers and happy Easter,
  Johannes
