-Added a new access type that will act as a weapon permit that the HoS/HoP can manage. Centcom, Security, Captain, HoP, and the Barman start with it. Securitrons will be checking against this instead of access_security.
-Securitrons will now have the option to declare arrests they make to anyone who is wearing a security HUD. Defaults to on.
-Securitrons now have the option to arrest humans without an ID. Defaults to off.
-Changed how securitron threat assessment is calculated
-Removed detective's access to securitrons
-Stunning and cuffing now properly bolds their text for the perp
-Laser/taser fire from ED209s will now emit sounds (They were completely silent before)
-Pingsky has its own type now

I realise there is a lot of existing duplicate code between the EDs and the securitrons, but that's such an enormous task to sort out that I don't think I can tackle right now.
This feature is never seen or used. Could you remove it please.
