protected property MigrateItemsXML::$cache_ids in Migrate 6.2

Given an XML object, parse out the IDs for processing and return them as an array. The location of the IDs in the XML are based on the item xpath and item ID xpath set in the constructor. eg, xpath = itemXpath . '/' . itemIDXpath IDs are cached. The list of IDs are returned from the cache except when this is the first call (ie, cache is NULL) OR the refresh parameter is TRUE.
