Subject: Allow to show video in fullscreen if requested.
X-Git-Url: https://git.owens.tech///git?a=commitdiff_plain;h=73fbd884bab5670e1593153df75697e82d174f8f;p=vimb.git

Allow to show video in fullscreen if requested.

If JavaScript calls element.webkitRequestFullScreen webkit switches vimb
into full screen mode. But the statusbar and the input box where still
shown. So now vimb hides the statusbar and the input box to allow videos
to be show on the whole screen.
