          HashMap needs a take() function that combines get and remove

        * wtf/HashMap.h: Added take function. Simplistic implementation for now,
        but still does only one hash table lookup.

        * kjs/array_instance.cpp: (KJS::ArrayInstance::put): Use take rather than
        a find followed by a remove.

        - use the new HashMap::take function where appropriate

        * bindings/js/kjs_binding.cpp:
        (KJS::addWrapper): Made an inline rather than a macro; inlines good, macros bad.
        (KJS::removeWrapper): Ditto.
        (KJS::removeWrappers): Ditto.
        (KJS::ScriptInterpreter::putDOMObject): Use the inline instead of the macro.
        (KJS::ScriptInterpreter::forgetDOMObject): Ditto. This involves using take instead
        of remove -- in theory ever so slightly less efficient, but I think it's fine.
        (KJS::ScriptInterpreter::forgetDOMNodeForDocument): Ditto.
        (KJS::ScriptInterpreter::putDOMNodeForDocument): Use the inline instead of the macro.
        (KJS::ScriptInterpreter::forgetAllDOMNodesForDocument): Use take instead of find/remove.
        (KJS::ScriptInterpreter::updateDOMNodeDocument): Use the inlines instead of the macros.
