Subject: [PATCH] few improvements to the video widget (yay for airport
 hacking): - add a seek slider to the control bar, that "becomes" a button
 that popups it when there is too few space for it - more robust even filter
 on the phonon video widget - "eat" the tooltip events, so we don't have
 tooltips coming from eg the page view
