Make camera monitors use the upgraded camera system

[Nnystyxx]

See title. The handheld camera monitors use the old nasty pick-off-a-list-and-reset dialogue, I'd prefer if they were just mobile versions of the new cameras.

Alternatively add a radio-style intercom to the cam room in the NSV Renanin radiostation because dammit I want to observe and comment on the station's haps.
