        Fix svg memory leaks.

        Reworked SVGList to deal with RefPtr's for ptr types
        which makes manual refcounting unnecessary, and is much safer.

        Removing all virtual functions (nullItem) from SVGList, and
        also remove SVGListBase. Switch to a similar concept like
        Vector/VectorTraits (see new file SVGListTraits.h).

        Credits go to Eric/Maciej for the inspiration.
