Some ammo fixes

- Fixes pirate gun not getting 12g caliber correctly.
- Fixes .357 caliber not being named consistently with everything else.
(Do not merge this until
https://github.com/PolarisSS13/Polaris/pull/3533 is merged pls, unless
Yosh fixes his caliber to be correct also.)
- Changes .50AE ammo to .44 because that's more consistent with what the
gun is capable of in-game, because it uses the same damage values as the
.357 and not a bullet that shoots through through your fridge, through
your house, and hits your neighbor's home invader like a .50AE is IRL.
The fact that it's .44 makes much more sense. This is purely a fluff
change because it annoyed me.
- Fixes a bunch of ammo.dmi icon names and makes the file not a jumbled
fucking mess. This means now your 762 mags and the newly renamed 44 mags
will not be broken anymore.
