Fixes issue #3401 by adding a helper proc to mobs which specifies whether a mob has the racial ability to eat and drink, and checks this proc in the "canconsume" reagent proc (called when someone is fed or tries to eat/drink).  Humans, aliens, and monkeys can all be fed food and drink as a result, and service borgs can no longer drink their own coolaid (to get diseases or otherwise).
Mobs will now slowly bop up and down while in zero gravity.
Replaces the serviceborg beer bottle with a drinking glass, adds beer to the shaker.  Emagging unlocks a second shaker with a different icon and description (but the same name) which dispenses beer2 (the disguise chloral) or mutagen or thermite.

MUTAGEN might be controversial I assume...  The service borg has no spray bottle though.

Moves update_robot_modules_display() to fix a UI glitch where using the home to unequip a module wasn't making the module appear in the storage list until it was otherwise updated.

Robots no longer take fire damage from fire stacks, since they're otherwise immune to heat... also, fire stacks will gradually burn off and the borg will stop being on fire.

Service borg emag beer (beer2) was oldchloral instead of newchloral.  Excellent argument against copy-paste.  Fixed.

Removed the dumb "if this happened to be a borg's drink container, refill whatever it's currently holding the most of after a delay" which lead to an easy reagent duplication glitch, and was generally shit.  Fixes issue #1673.

Uncapitalized some drink names which weren't proper nouns, and changed stuff like "Beer glass" to "glass of beer".

This still fixes #3401 too of course
Merge branch 'master' of https://github.com/tgstation/-tg-station into Issue3401

In monkey.dm my SpeciesCanConsume check was conflicting with a new canBeHandcuffed check.  All resolved now.
Changes beer2 back to being oldchloral (but keeps the new reagent-metabolism-speed check), and removes the duplicate beer from the shaker (but still moves it to the front of the list).
Removed mutagen from the emagged service borg shaker, for now.
Improved bomb logging

-Logging added for activating timers attached to transfer valves
-A quick link to the Signallers list has been added to bomb logs involving signallers

Conflicts:
	code/modules/mob/living/carbon/monkey/monkey.dm (resolved)
Fixed #3077. Singularity now sucks small items instead of large ones.
Makes this actually work properly. It's always harder than it looks.
Syncing a robotics fabricator no longer clears its queue
Standardizes pill.dm
Makes pill devouring code much better
* Added a "stop pulling" button to monkeys and alien larva
* Make aliens use their hud "intent button".
* Make monkeys use the current selected (e.g midnight) hud "intent button".
fixes exploits with the mech fabricator (/tg/)

this exploit is in all public builds i could look at.

using the mech fabricator, and you were able to duplicate any obj in the server.

as a nice bonus you could also abuse the part-description-function to identify any atom in the server
memory for even easier access to other yet unknown exploits of this kind.

and also range check was missing to make sure you are not on some other z level massproducing guns.

i will not go into details, as it is exactly the same kind of exploit over and over, 
so if you are interested on how and why these exploits work, see some of my other exploit commits :
https://github.com/tgstation/-tg-station/pull/3416
https://github.com/Baystation12/Baystation12/pull/5068

i advise any coder team to be supercautious when changing/writing new Topic procs to prevent these,
and to always doublecheck other coder's works.

fixes exploits with the mech fabricator (/tg/) v5

more brainfart removal.
in retrospect i should have cloned this build for compiler handholding.
