M10 Auto Pistol (#7569)

# About the pull request

Adds the "M10 Auto Pistol" as a primary "side-arm". Gives it a custom
holster much like the m39 one, but can hold only the M10 + 8 magazines
of "pistol ammo". Also adds various M10 ammo types boxes, normal HV,
extended and drum (even larger extended).

Also side-note - also fixes the broken m39 holster gun camo icons and
adds the missing "urban" and "jungle" too.

Tested the gun, may need some tweaking, but it works well as a
hyper-fast-firing side-arm with low damage, should be fun.

Also the guns sounds/balance may be up for change if necessary,
especially the sound.

# Explain why it's good for the game

Basically for a while now I've always wanted a new type of "SMG", I
requested that someone make one, instead I got the M10 - Auto Pistol,
which is equally as cool as a new SMG, and perhaps even more unique.

We don't have any types of fully automatic pistols, and it's something
that I'm sure players would enjoy, as it's more of a side-arm then a
primary weapon like the M39 is currently.

Generally it won't change much in the gameplay loop, rather just give
you an additional option of playstyle. It will really just be an
interesting alternative to the current side-arms, without taking away
what makes them unique but being unique in itself.

It also is lore-accurate to the games at least. Here's the wiki-page for
it if you want more specific information:

I want to thank **Frans_Feiffer** for their amazing sprites, without
them this whole thing wouldn't have come to fruition.
