MakeWireEnt prototype

This is a draft of a potential MakeWireEnt function, which would replace all the various MakeWireWeight global functions currently in use. Its trimmer, would result in much less code duplication, and is compatible with Garrydupe and Map saving (and of course backwards compatible with Advdupe).

By making WireToolObj's default MakeEnt function use MakeWireEnt, it trims down stools too.

As a demo, I switched the Weight and Text Screen over. The Weight ent was just deletions, though the Text Screen had a little check in MakeWireTextScreen I had to move over to Setup.
