        - FloatingObject cleanup

        Renamed FloatingObject's data members as follows: node -> m_renderer,
        startY -> m_top, endY -> m_bottom, left -> m_left, width -> m_width,
        and noPaint -> !m_shouldPaint, reversing the meaning of the flag.

        Also addressed the FIXME in RenderBlock::containsFloat().

        (WebCore::RenderBlock::addIntrudingFloats):
        (WebCore::RenderBlock::containsFloat): Changed to return false if the
        floats lists exists but is empty, since line layout code no longer
        relies on the buggy behavior.
