About the pull request

Adds CMB Riot Control Unit, a riot supression/swat oriented unit, with equipment in between of lethal and non lethal, which makes them capable of fighting xenos more or less effectively.

Their looks are mostly made up, but spec visuals are based on an artwork made a while ago.

Added CMB Riot Control Unit ERT with a chance of spawn equal to CLF, PMC, Private Military Contractors, and others.

Resprited CMB badges:

Left old, right new

Reference badge for example:

Also added id card mob sprites for these badges:

Added unique berets, helmet, armors, unifroms, helmet visor for the new unit.

Added new jobs: CMB Riot Control Officer, CMB Riot Control Synthetic, CMB Medical Technician, CMB Breaching Technician

Added custom black Spearhead revolver for Marshals, it has the same stats but different sprite, but most importantly, it can perform revolver tricks.

Added actual working CMB squad icons and made CMB utilize their own hud, instead of marine hud (people can just swap headset to marine one if they want marine hud).

Cleaned up some broken chunks of marine hud code.

Fixes mp5 (copied from uzi), m81 gl (draw myself), m37-17 (it was in file, but named wrong) suit storage sprites, these will no longer be invisible while stored on armor.

Made some variations of belts, pouches, etc for the new unit.

Tweaked sec hud sprites of investigator cmb synth.

Tweaked normalpoint Spearhead bullet, added 15 damage to it (from 45 to 60), hp bullet has 75 damage (unchanged), and normalpoint one lost in damage output in scenarios where it should be winning, now normalpoint does better against armored targets (dealing 69 damage, 15 ap), hp one against unarmored (dealing 86 damage, 0 ap).

Tweaked mob sprite of SWAT sec hud goggles, because it was completely unrelated to the icon.

CMB synth and deputy survivors on Fiorina have been swapped for their riot control analogues, which completely matches their backstories.

All CMB survivors are now correctly of CMB faction and faction group.

CMB Armory on Solaris Ridge now has CMB Riot Control gear instead of generic riot gear.

CMB Armory on Trijent Damn now has CMB Riot Control gear instead of generic riot gear.

UA Armory on Fiorina now has one cmb locker, also added one CMB Riot Officer corpse on the map.

Added M16A5 (M16), CAR-15A3, (XM177), MP5A5 (MP5) reskins for the new unit, will add them on planetside where they fit in another pr.

Added new set of backpacks for the new unit, will add them in other places later.

Added blocking visuals and new sounds. Mostly a port of tgstation/tgstation#74998.

Most of the equipment is correct with the xenopedia CMB article.

Majority of sprites by Crowford, discord tag sir.crow.

Hud sprites, m16a5, mp5a5, car15a3 sprites by me.

Explain why it's good for the game

Better variety, more content, adds intermediate ert between anchorpoint marines and cmb patrol, like the author of cmb ert intended.

Equipment and balance might need to be tweaked tho.
