The same as https://github.com/PolarisSS13/Polaris/pull/3612 except this
time I'm not a dumbass and accidentally overwriting other changes
because the Github client decided not to sync with Polaris.
My reasoning behind this request is because, aside from a small armor
pen value, a puny little .45 pistol is better in every other way to a
bolt _rifle_, and that just doesn't make any sense, and isn't very fun.
It basically just exists as a lousy gimmick right now.
This PR makes it slightly less of a gimmick and more of a weapon people
might actually use if they don't have many options. This weapon is
especially popular during cult rounds when Cargo needs some kind of
guns.
ToDo: Fix the Lever rifle to not have speedloader ability. Also, why
does the Lever rifle already use 7.62 ammo? Did anyone know this?
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.
