        Added two layout tests for regression testing.

        - redid frameElement (fix for 4091082 below)

        The first version lacked a security check, and was also broken.

        * khtml/ecma/kjs_window.cpp:
        (frameElement): Refactored into separate function; added isSafeScript check.
        (Window::get): Call the new frameElement function.

        * fast/frames/frameElement-frame.html: Added.
        * fast/frames/frameElement-frame-expected.txt: Added.
        * fast/frames/frameElement-iframe.html: Added.
        * fast/frames/frameElement-iframe-expected.txt: Added.
        * fast/frames/resources/frameElement-contents.html: Added.
