Shotgun additions and minor tweaks (#3554)

* 24-round shotgun mag fixes + making it relevant.

Adds the AS-24 Shotgun to the traitor uplink for 100 TCs, also makes automatic shotgun magazines costs the appropriate amount (13,000 metal up from 2200)

* Magazine variety.

Nothing really new here. Beanbag / pellet mags for the admin-only AS-24.

* shotgun 6-shell clips, autolathe and shotgun tweaks.

+6-shell quickloader clips for shotguns, with proper metal costs for slugs, beanbags and buckshot.

+minor tweak to shotguns to allow the quickloaders to work in a non-silly way (load_method = SINGLE_CASING|SPEEDLOADER) since there are literally no other shotgun speedloaders this probably shouldn't be an issue (as it's ever so slightly quicker than loading with a box)

+added sprites for quickloading clips.

* Requested changes.

-6 round shotgun clip sprites
+4 round shotgun clip sprites
-/+ adjusted shotgun clips to 4 rounds

* cherrypicking

* fixes

did a bad

* literally a number
