Previously, VLC would assume 4/3 picture aspect ratio. That was quite
lame. This patch makes --v4l2-aspect-ratio redundant.

This disables driver-specific modes that VLC would not know about.
This also disables high quality (i.e. still camera) mode since we want
video, as well as other any other future abnormal modes.

Somewhat fixes a big usability problem: tiny buttons, unrevealant icons
and associated text shown as tooltip.
We now reveal all text on mouseover.

We will get more and more of those samples soon...

No sense to display chapter buttons with 1title&1chapter
