Added GetDisplayNames capability. For now, we don't actually use display names, and this cap returns the regular name. But this moves the server side into the newer, preferred, protocol used by the viewer for fetching the names of agents in the scene given their UUIDs. (the old protocol is via UDP). This works fine in my limited tests, but could use further testing by others.
