We have to differ between the initialization and the
'page entered' and 'page left' event.
This avoids that all VideoWidgets with poster image show up
on first slide or do no disappear when changing slide.
With this commit Okular will show a so called poster image for PDF documents
containing movie annotations. The image will be a screenshot of the first frame
of the video.

FIXED-IN: 4.10.0
Use the auto play property of movies that are not started via
the 'page open' action. That's the case for Rendition-based videos
from PDF documents for example.
- 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
