Title: Fullscreen updates to viewer.js for latest (unprefixed) spec.

Fixes the camelCase error in requestFullscreen (`requestFullScreen` -> `requestFullscreen`). Replaces `document.fullscreen` with a check for a non-null `document.fullscreenElement`.

This allows the fullscreen button to work in Opera Next (what will be Opera 12.10), which implements a newer version of the spec sans prefix.
