[MAP]Minor Map Changes/Assistant Spawns

Re upload due to merging conflicts with the last PR.

Little has changed since my last update from the prior PR here: https://github.com/tgstation/-tg-station/pull/4881

Detective's SecHUD's were removed as requested, in addition the Gulag Securitron was moved back to the Gulag. I will revisit those ideas at a, far, later date.

The following changes have been made

* Assistant Spawns have been changed, now Assistants will spawn all over the station, from outside Medical, the bar to the Chapel.

* The Research and Development Room now has two Privacy Shutters in the southern entrance, to replace the removed tinted windows.

* The Brig entrance now has a wall mounted flasher that is activated from the entrance checkpoint. Great for crowd control and getting rid of people inside the brig.

* Incinerator room has as second entrance to its south, connecting the entire Maint loop.

* A whole bunch of missing pipes have been removed, bug fixes and all that jazz.

* Add myself to the admin's list for convenience.

* Execution Room changed in design and usage, gas chamber is now a electric chair. The chair itself needs to be assembled but all needed components are present. This is to prevent errors associated with a preset electric chair.

* AI Satellite Maint room has a motion-sensitive camera.

* Hand Labeller added to the Warden's Office.

* Crew monitoring console added to the Warden's Office.
