Refactor

- Deletes Paranormal & Janitor ERT outfits from /datum/outfit/admin (so
they won't show up in the main special outfit list as *static* outfits)
- Adds Paranormal & Janitor ERT outfits to 'emergency response team
member' sub-section of admin dress command, which means they're still
available, but now you can choose the level of them to equip to someone
(amber/red/gamma), instead of them always being the old static outfit
which doesn't match what real ERT actually use anymore.
- Refactors the way that spawning ERT cyborgs works, so that most of
their special stuff is done in New() instead of in response_team.dm.
This means that manually spawning an ERT cyborg will actually work,
rather than generating a half-ert cyborg with much of its special stuff
missing.
- Adds a new subtype of ERT cyborg, /mob/living/silicon/robot/ert/gamma,
which is absolutely identical to the normal ert borg, except that it
always has gamma module unlocked.  This enables admins to manually spawn
ERT gamma borgs, instead of all ERT borgs spawned always being non-gamma
ERT borgs.
