Attempt to prevent the gateway from derailing rounds as much.

add: The station's gateway has been equipped with safeguards that prevent critical employees, the heads of staff, from abandoning the station. It also requires a Captain or CentCom level ID to engage the wormhole. These restrictions do not apply when an emergency state is detected.
admin: You can disable the safeguards by var editing the gateway and setting safeguards to 0.

[why]: Since map template loading is getting revamped and people are remaking/adding away missions so that they are no longer loot pinatas, I figured I'd add a small stepping stone for turning on the gate, also preventing heads from leaving 4noraisin because they are critical to round progression.
I added the var override for admins so they can run events easier.

If heads of staff are abandoning the station to go on loot trips without regard for the station it can be dealt with administratively.
There is no need for a hardcoded lock. Even revheads can leave the station via mining shuttle if they wish (it's just a one-time warning message if they try, it succeeds on next press), I don't see why this should be any "stronger" in terms of protection.

A captain leading an expedition is pretty captainly really.

@kevinz000 apparently admins didn't want to deal with it before hence the removal of the away missions because "muh derailed rounds".

If people really want I can remove that part but keep the ID lock to turn it on.

Wait, who are the usual suspects of "code solutions" and "administrative solutions" again?

[DaxDupont]

Actually, I have a better idea for away missions, let's make it more accessible.
