Add Gas Grenades

[AutumnNova]

Notes:

Basically just a grenade with an internal tank that dumps it onto the tile its on
Very useful for rapidly refilling a room lacking atmos (or filling a room that has atmos with whatever terrible gas you want)
Filled (or refilled) by inserting into a gas canister just like you would an oxygen tank
Adds 2 empty ones that spawn in the EngiVend on roundstart
Comes with a colored overlay that changes depending on the contents of the grenade

(From left to right, Tritium, CO2, Plasma, Oxygen)

Also adds a way to prevent gas containers from being used as a source of gas for gasmasks, because you really shouldnt be hooking up a grenade to your gasmask

Changelog:

CL: [New] Adds grenades that can be filled with any gas.

Could you add the empty variant to the autolathe? Would be nice to be able to manufacture more.

To add it to the autolathe, just go to one of the designs json file in StreamingAssets and add a new entry; like this:

 {
        "Internal_ID": "largecrossbow",
        "Description": "A reverse-engineered energy crossbow favored by syndicate infiltration teams and carp hunters.",
        "Category": [
            "Weapons"
        ],
        "Materials": {
            "Metal": 5000,
            "Glass": 1500,
            "Uranium": 1500,
            "Silver": 1500
        },
        "Machinery_type": [
            "ProtoLathe"
        ],
        "Compatible_machinery": [
            "Security"
        ],
        "name": "Energy Crossbow",
        "Item_ID": "/obj/item/weapon/gun/energy/kinetic_accelerator/crossbow/large"
    }

Item ID is always usually the GUID in the prefab tracker component of a prefab.

To add it to the autolathe, just go to one of the designs json file in StreamingAssets and add a new entry; like this:

The autolathe actually just references the prefabs directly as it isnt part of the techweb. Design files are only needed for machines that use the techweb

[MaxIsJoe]

in that case ignore that part and just add its prefab directly to it (not sure what that list is)
