Gives Malf AI the lockdown ability!
Removed unneeded checks and commented code.
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).
Lowers CPU cost of Hostile Lockdown to 20!

It might not have been as powerful as I thought it was, so halved the cost of it!
Fixes a minor mistake.
Changes instances of "usr" to "src"

Just doing a minor cleanup.
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
Adds a check to ensure the airlock is powered.
Removed a pointless check.
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
Adds a cool-down for Hostile Lockdown.
Optimization changes

Adds all doors to the "portals" list.
Optimizes the lockdown loops.

Since all doors are now in the portals list, it can now efficiently be searched by the for loop, and subjected to only one istype() check.
Furthermore, since all doors have an open and close proc, there is no need to separate firelocks and blast doors.

This has the added bonus of making the lockdown somewhat harder to notice.
Merge branch 'master' of https://github.com/tgstation/-tg-station into Issue3401

Conflicts:
	code/modules/mob/living/carbon/monkey/monkey.dm (resolved)
Adds missing stat (power) check.

This is to make sure that firelocks and blast doors are not triggered if they lack a power source.
Fixed #3077. Singularity now sucks small items instead of large ones.
