Let players modify access of individual turrets

[mvanalphen]

Changes:

1. Players can now modify the req_access/req_one_access on turrets that aren't connected to a turret controller. This allows players to set up turrets for specific areas such as the armory.
2. Fixes a runtime with communication computers when an AI tries to log in.

I don't suppose there can be a way to modify what mobs it aims at.

Because it's really annoying setting up turrets to protect against Xenos and have them start firing on civilians because someone decided to bring a Nymph with them.

Not specific mobs, no. The "Check Misc. Lifeforms" setting simply shoots anything that is non-human, and having it target specific mobs would become a bit snowflakey (we'd have to generate a list of custom mobs, as giving players a full list of non-human mobs wouldn't work very well). Nymphs should just avoid turrets :P.
