[DO NOT MERGE] Adds many gun-related changes and new things

- Adds tommy gun, stun revolver, and retro laser to 'summon guns'.
- Adds virtually all projectile weapon ammo types in boxes to hacked autolathe, including:

 .45 for the uzi, tommygun and upcoming m1911
 9mm for the protolathe smg and upcoming glock
 12mm for c20rs (if you get one, you lucky bastard)
 7.62 if it's really really lusted after but not a lot of people get l6 SAWs
- Tweaks and rebalances magazine ammo counts to be more realistic/balanced (.45 magazine for the m1911 is now 8 round, for example)
- New icons to differentiate ammo box types from autolathe (ugly codersprite recolors, anyone can redo these down the line)
- Adds upcoming m1911 .45 to protolathe for a direct magazine size and 5 brute upgrade to the detective's revolver if the stun revolver is too casual for you
- Descriptions, mineral amounts, and research requirements tweaked for the SMG and new m1911 (I just buffed the mineral drop rate to go along with this a little)

Don't merge this, needs some additions and tweaking once dannos is done with the m1911.
