ammo expansion + moar guns

Description of changes

This PR adds the .22LR, .45, and 5.56x45mm bullet calibers. Additionally, it adds two new .22LR guns - the Rimfire and Zip. Each caliber comes in two tiers, 'makeshift' and 'standard'.

All guns which used 10mm (or 'pistol' caliber) now use .45. This includes the Colt, Colt-M, Chief, and Underdog.
All guns which used 5.56 (or 'rifle' caliber) now use 5.56x45mm. This includes the Minuteman and Mosin.
All guns which used .50 (or 'shotgun' caliber) now use 12g. This includes the Slider, Bouncer, and Teufort.

Various minor tweaks to some guns have been made across the board.
Legacy ammunition types have been disallowed from printing due to them being useless now that they don't fit in any printable gun.

.22LR Rimfire (tier 1)

.22LR Zip (tier 0)

12g Bouncer [Sawn-off variant] (tier 1)

Why and what will this PR improve

The new ammunition systems encourage more time being put into research - low-quality ammunition is cheap and easy to research, but isn't very effective. Better tiers of ammo cost more research and supplies to acquire, but are more effective. The same goes for magazines, which are researched in the same way.

Having our own ammunition system allows us to easier tweak it than trying to work around the Nebula-based ammunition system.

Magazines are now universal based on their caliber rather than being build specifically for one gun. This makes researching a .45 magazine far more useful if you plan on using .45 weapons, without locking the player into one gun just because that's the only gun they've researched the specific magazine for.

Success!

Willing to give this a shot. In the future I'd like to balance projectile weapons with more complicated material costs (brass and gunpowder), but these changes seem to be a good start.
