The entityselector widget constructor can be found in jQuery.ui.entityselector. Since it is not a generic low-level UI widget and rather wikibase specific, it should be moved into jQuery.wikibase.entityselector instead. Wherever the entityselector is currently used should not be affected since usually a jQuery bridge is registered and used as jQuery.fn.entityselector.
