- a few baby steps to try to make lockHistory and userGesture less confusing

        * page/FrameLoadRequest.h:
        (WebCore::FrameLoadRequest::FrameLoadRequest): Add initialization of m_isUserGesture
        to true.
        (WebCore::FrameLoadRequest::shouldLockHistory): Renamed from lockHistory to avoid having
        a getter that sounds like a verb phrase.
        (WebCore::FrameLoadRequest::setShouldLockHistory): Ditto.
        (WebCore::FrameLoadRequest::isUserGesture): Added.
        (WebCore::FrameLoadRequest::setIsUserGesture): Ditto.

        * loader/FrameLoader.h: Remove userGesture parameter from load that takes
        FrameLoadRequest. Remove default values for lockHistory and userGesture parameters,
        since that just makes it more likely we'll forget to pass them in. Remove one of
        the overloads of urlSelected, since it's only called one place.

        * loader/FrameLoader.cpp:
        (WebCore::FrameLoader::createWindow): Remove userGesture parameter, relying on
        the true default in FrameLoadRequest.
        (WebCore::FrameLoader::urlSelected): Call setShouldLockHistory and setIsUserGesture
        on the FrameLoadRequest, and call load directly; also eliminate the other urlSelected
        overload since this was the only place it was called.
        (WebCore::FrameLoader::load): Remove userGesture parameter, relying on the true
        default in FrameLoadRequest. In the other overload, clean up logic to eliminate the
        argsReferrer variable and get rid of the userGesture parameter, using the value from
        FrameLoadRequest.
        (WebCore::FrameLoader::submitForm): Remove userGesture parameter, relying on the value
        in the FrameLoadRequest. This actually changes behavior.

        * bindings/js/kjs_html.cpp: (KJS::JSHTMLDocument::putValueProperty): Pass
        false for userGesture explicitly instead of relying on default argument.

        * page/ContextMenuController.cpp: (WebCore::ContextMenuController::contextMenuItemSelected):
        Remove userGesture parameter, relying on the true default in FrameLoadRequest.
