General manufacturers: ammo not available anymore

[Sam Guivene]

The schematics are unfortunately still broken, and it would be nice to have an alternative source of ammo again. It would be appreciated if a coder could have a look at this bug.

Manufacturer: Schematic "/datum/manufacture/stunrounds" not found
Manufacturer: Schematic "/datum/manufacture/bullet_22" not found
Manufacturer: Schematic "/datum/manufacture/bullet_smoke" not found

Is there any way a short term fix could be made? Such as a minor rollback in allowing charcoal back into the game, or an ammunition crate to be implemented? As .22s are in very high demand in station, both for zip guns and for spies, and stun round/smoke rounds are also pretty high demand items.
