Neuter alternate methods of entering fullscreen mode when in metro snap (via extension and via JS fs api).
Correct appearance of fullscreen bubble when moving from fullscreen non-snap to snap to non-snap.
BUG=130623
TEST=Open metro chrome. Enter fullscreen mode. Enter metro snap mode. Exit metro snap mode. Observe fullscreen is exited, no bubble appears. Also, visit a page that uses JS or extension APIS to enter fullscreen mode while in metro snap. Observe that those API calls do not enter fullscreen.
