Nuke Op Population Scaling and Content Update

to be edited
-Adds an exclusion list to uplink datums. Previously, if you wanted to exclude an item from just one mode, you would have needed to list ALL other modes; hindering maintainability and generally being a pain.
-Mauler primary weapon replaced with the machine gun. I would prefer to replace this with a single-shot heavy cannon at some point in the future.
-Adds Gygax as a light exosuit option.

-Map edit, adds the nuke op TC consoles and updates the ops staging area.
Fixes up the implant removal messages, replaces names with paths in uplink_item.dm
Merge branch 'master' of https://github.com/tgstation/-tg-station into pr/1701
