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.
Fixes certain guns being unremovable due to unloading ammo taking
precedence over picking up. Also adds on-back icon for the merc sniper
which is just a copy of the LWAP's.
Tweaks syringe gun and dart gun, renames syringe gun cartridges and makes them printable.
Adjusts penetration so that passing through mobs happens with a probability that scales with damage.
Adds a .45 signal pistol to the HoP's closet and a 9mm one to the mercenary shuttle.
Makes syringe guns a type of launcher gun, and removes the hack
projectile.
Also moves syringe and dart gun source files into the modules/projectile
folder.
