- replaced CDefObjInfo with ObjectTemplate class - ObjectTempate is a direct member of objects instead of pointer with shared ownership across CMap, handler and game objects - simplified handling of objects that can change appearance (e.g. towns) - all object queries regarding object appearance/blockmaps use h3m pos instead of relative positions - removed need of modhandler::reload - cleanup of some old code
