Drone assembly can be made in RnD now.
Adds injector component, which does what it implies, and injects a reagent into someone or something nearby.
Adds reagent pump, similar to the above but meant for moving reagents around different containers, inside or outside of the machine.
Adds adjacent locator, which can find specific objects next to the machine.
Adds two flavors of the reagent storage component, which does what it says. The second variant is a cryo-beaker version.
Ports PsiOmegaDelta's port of integrated circuits, which has several improvements in code quality.
Ports a few small things like the weakref datum and some macros.
A lot of new defines are now in inventory_sizes.dm, which contains;
All the size identifiers (the thing that tells the game if something is bulky, or w/e).
Storage costs for all the sizes, which are exponents of two, as previously.
A few constants for inventory size.
Also changes all storage item's capacity definitions by basing it off of how many 'normal slots' exist for it. This allows one to change the definition for all of the defines in the file, and everything will follow along without needing to change 500 files. In testing, I made all ITEMSIZE_COST_* defines doubled, and nothing had broke.
The benefit of doing all of this is that it makes adding new weight classes in the future much simpler, and makes knowing how much space a container has easier, as seeing ITEMSIZE_COST_NORMAL * 7 means it can hold seven normal items.
The ability to ventcrawl is now checked by the /handle_ventcrawl() proc, making it possible to properly check before and after the do_after() call.
Moves various checks into the base can_ventcrawl proc.
Now lists the first object that prevents a mob from ventcrawling, making it easier to correct the exception list.
Removes the issmall() check, instead checks if the crawling mob has the relevant verb. Fixes#14081.
