fixes #1512, fixes #1507

On ended, pause player if not paused or looping
IE11 (and maybe other browsers as well) only fire 'ended' event when the
video ends and doesn't fire pause. This makes IE11 not reset it's state
into a paused state that allows a user to replay immediately. However, a
two clicks on the play/pause button will allow you to replay.
In Chrome, we get first a pause event and then an ended event. When
'loop' is set, neither the last pause nor ended fire.
In the flash tech, the pause and ended events fire like in chrome in all
browsers.

Add tests for onEnded change

Appease jshint.

    Listen via 'this.one'.
    Don't bother checking whether the video element is fullscreen but just
    assume we are fullscreen.

    Don't trigget vjs's fullscreenchange event
    This event isn't really being used for this usecase right now, so, no
    need to trigger it.
