Nexus changes

Title of Suggestion: Nexus changes

Description: Implement several changes to the Nexus, these would include:
- Make it so you no longer can lock the nexus lobby doors.
- Make it so you no longer can lock the elevator doors.
- Make it so Nexus front defenses are no longer allowed. only allowed with a dictatorship.
- Nexus is considered a public building, so it should be treated accordingly --> No unrealistic defenses inside.
- Nexus Elevator defense should be allowed as long as it's fitting.
- Nexus Garage defense should be allowed as long as it's fitting.
- Nexus Slope defense should be allowed as long as it's fitting.
- Nexus Garage elevator defense should be allowed as long as it's fitting.
(With "fitting" I mean defenses should be realistic and fit inside the building and its style; eg. no unmaterialized metal plates or borderline doomfort etc.)

Why: Let's face it. Nexus defenses ruin a lot of interaction. The nexus is considered a public building, and should in my opinion be treated as one. In the current "meta" people set up massive dupes at the nexus front, removes the entire purpose of the nexus lobby and anything it has to offer. It COMPLETELY removes the purpose of the nexus FRONT DESK secretary. It almost completely defies interaction between citizens and presidents as citizens try to get in contact with officers and SRU instead, which is in my opinion just stupid, as these should not be considered contactpersons for the President. 

Here's an example, although this would be considered a low security defense with more of an aim towards RP.
