Title: Bind openfl.external.ExternalInterface#call to proper this in html5 backend.

This change makes ExternalInterface#call in html5 backend work in a similar way to flash backend.

In flash, whenever you call ExternalInterface.call('ns.object.method'), the method will be called with ns.object as 'this'.
In html5 currently this would be just 'window'.
