Done. - PMPrototypeManager and PMInsertRuleSystem are no singletons any more, the part has how one instance of each. - All objects have a pointer to the part now (needed to access the insert rule instance) - To reduce memory consumption the meta object (PMMetaObject) has a factory method to create new object instances, the newObject factory methods are removed. Therefore the prototypes can be deleted immediately in the PMPrototypeManager::addPrototype call.
