Bot fixes!

- Fixed an issue where unlocked bots continued to refuse On/Off command
to unauthorized users.

- Centralized AI bot calling code a bit for the bots.

- Changed emagging/hacking logic such that hacking a bot still works if
the interface is emagged to an unlocked state, but the bot itself is
not.

- Fixed an issue where a bot that has been unlocked by an emag by not
actually emagged would show as emagged to the silicons.

- Floorbots no longer attempt to build in space or shuttle docking
areas.

- Floorbots will now make tiles from metal sheets of any amount, not
only single sheets. It will convert the metal into tiles only one sheet
at a time
Robotics bot access increase + beacon tweak

- Navigation beacons now use the sexier black UI.

- Roboticists now have access to navigation beacons, floorbots,
cleanbots, and medibots.
Map bots edit!

Sec gets access to Sweepsky, Med gets it for Scrubs!
*Fixes a rather amusing bug where super high potency deathberries would be actually less deadly and not contain any ehuadol.
Fixes the escape sec office missing a door.

What the title says. I'm amazed this hadn't been fixed for so long. Also adds myself to the changelog credits as I've been working with the whole TG/NT thing for about 3 years now.
Adds four new chemicals.

Bath salts: Simple chemical that brings your drunkness to absolute max while significantly reducing stuntimes.
1 universal enzyme, 1 space cleaner, 2 vodka = 2 units.

Pentetic acid: Not a drug, real medicine that heals 5 rad and 3 toxin damage per cycle.
1 ammonia, 1 chlorine, 1 radium = 1 unit.

Almazidone: Causes intense hallucinations, flashy colors, and twitching while causing 3 oxyloss and 1 random organ damage per cycle.
1 welding fuel, 1 toxin, 2 sodium chloride = 3 units.

Elatopam: Branded as an old medication to heal bruises and burns, now it's used to get high. Heals 1 burn damage and randomly heals 1 brute damage per cycle. Does 1 brain damage per cycle, causes jitteriness, and causes flashing colors.
1 virus food, 1 robust harvest = 4 units.
