This patch moves the "fullscreen" event from the original place to the second part, which indicates two other changes: 1. When the event is triggered, the value of fullScreen would have been toggled to the new value, which is different from before. The changes in browser/../browser-fullScreen.js and mobile/../browser.js are for this. 2. This event is no longer preventDefault-able, since it is triggered after the fullscreen change. This leads to the removal of the test and the only place which calls preventDefault on that event. That place is a workaround for bug 1079222. To address that problem, this patch fixes the intrinsic issue via stoping handling the fullscreen change once it finds we failed to change the state of the widget.
