[MERGED PR] Adds the Security Assistant job

[Boxta]

The security alert could have a much bigger impact than it appears because now you can just jam a button to let people know you are in trouble. This is much much faster than trying to send a radio message or use the PDA messenger. Even if an antagonist has rendered you unable to speak from crit or poison so long as you are standing you can tap it and it's not unreasonable to use it mid fight compared to the radio.

All PDAs already have an alert program

You have to be able to use your pda, and open it to use said program
