Adapt Element fullscreen events to new structure

[queengooborg]

This PR updates the fullscreenchange and fullscreenerror events of the Element API to conform to the new style. Additionally, this performs some updates to data for the Document API's events to make the two articles more similar to each other (since they already are so similar).
