Pass fullscreen option correctly to html5 youtube player

It seems that fullscreen parameter is not passed correctly to Javascript object to replace embedded player with html5 player if available.

This property is passed in javascript as:

$JSObject.fullscreen = {$variables['fullscreen']};

I propose adding it in $JSObject.options, with values 0 or 1 (instead of false or true), just after autoplay setting.

I attach a patch against 7.x-1.0-alpha5 version (sorry, I couldn't install dev version, I got errors). But error is applicable to 7.x-1.x-dev too.

Regards.
