Circuity improvements and minor additions (#18046)

* Implement circuitry bug assembly

* Add distant ref grabbing support to circuits

* Set circuitry clothing wearer var for some functionality

* Add silent, built-in speaker to circuitry ear piece.

* Communicator support and reference grabber circuit

* Add toggler circuit to easily toggle functionality

* Allow reagent using circuits to use reagent storage.

* update .dme
