        Ignore document.write() when it comes from a network task
        https://bugs.webkit.org/show_bug.cgi?id=47560

        write()s from deferred scripts are now ignored. This matches the latest
        Firefox 4 beta behavior. The defer-write expectations are updated, and
        the other tests are now all moot since deferred scrits can't write().

        * fast/dom/HTMLScriptElement/remove-source.html: Added. Verifies that writes are still ignored when the src is removed after the script is requested but before it is executed.

        This implements the update to the spec made by:
        http://www.w3.org/Bugs/Public/show_bug.cgi?id=9767

        It also matches the latest Firefox 4 beta. The notable change is that
        document.write from a deferred script no longer works. This avoids
        blowing the patch away.
