Update by Lagius:

Admins cat see if other admin has left the game.
The game actually checks for configuration variable guest_jobban  (still be turned on by default).
Added white list for heads and some non-heads (as in guest jobbans). Add keys to file data/whitelist.txt and turn on the option USEWHITELIST in config.txt.
Cyborgs were added to the list of important jobs (for guests jobbans and whitelist).
