Add Caddy CCT conduit trapeze to trapeze family or make separate family

These trapeze brackets are nice since you don't need to worry about strut straps. They are made by Caddy and SP products (there may be others). If they were in the trapeze family (or a separate family) they could be auto placed using the hanger placement tool.
