Support for #408: * added slot-0 LC and Saturn 128K for Apple II and II+ * added save-state support - for slot-0 LC/Saturn, save the LC state in the slot-0 card, not the //e MMU; and switch to a new Apple2 unit ver2 * added g_Slot0, g_SlotAux * added new LanguageCard.cpp/h to project and moved Saturn code into these new files. * updated VS2013,2015,2017 projects
