[BlackBerry] Automatically go fullscreen on video play

[Max Feil]

There is a requirement to have HTML5 video automatically enter fullscreen when the video starts playing. This patch implements this feature, with restrictions. The main restriction is adherence to WebKit's philosophy of only entering fullscreen due to a user gesture. This is important in order to avoid pop-up advertisements and other unwanted fullscreen content. One consequence of this is that video elements with the autoplay attribute will not automatically enter fullscreen.

Other caveats:
- This feature applies only to "small screen" devices where automatically going fullscreen makes more sense.
- Fullscreen will only be entered automatically when the video is played from the beginning (current time is zero). It is assumed that if the user is resuming play from a paused state and is not in fullscreen mode, then they exited fullscreen mode intentionally.

Marking r+, but I would prefer the name change.

I think it would be better to flip the meaning of the name so you ask if fullscreen is allowed instead of restricted. Maybe "mediaPlayerIsFullscreenAllowed", or "mediaPlayerIsFullscreenPermitted"?

Marking reviewed based on r+ given to previous patch. The only change in this patch is a simple one to rename boolean function mediaPlayerIsFullscreenRestricted() to mediaPlayerIsFullscreenPermitted() and change its sense.

Hate to be pedantic, but this does not match the renaming.
