Nixed a few more redundant loading functions in Frame. Did my best to update
        the non-Mac builds.

        * bridge/mac/FrameMac.h:
        * bridge/mac/FrameMac.mm:
        (WebCore::FrameMac::urlSelected): Kept always 'true' argument for userGesture
        always 'true', because changing it broke the world, and testing seems to
        indicate that the one caller that might have passed 'false' didn't need to.
        * page/Frame.cpp:
        (WebCore::Frame::requestFrame):
        (WebCore::Frame::frameLoader):
        (WebCore::Frame::redirectionTimerFired):
        * page/Frame.h:
        * platform/gdk/FrameGdk.cpp:
        * platform/gdk/FrameGdk.h:
        * platform/gdk/TemporaryLinkStubs.cpp:
        (FrameGdk::issueCopyCommand):
        * platform/qt/FrameQt.cpp:
        * platform/qt/FrameQt.h:
        * platform/win/TemporaryLinkStubs.cpp:
        (WebCore::FrameWin::shouldInterruptJavaScript):
        (WebCore::FrameWin::issueCopyCommand):
