[CLOSED PR] Halfs material cost for .22 magazines

[Carbadox]

I think it's counter intuitive that the update that removed .38 stunner from hacked fabricators also kept .22 bullets material cost unchanged. This was along side changes to no longer being able to get stun batons from destroyed securitrons and as well point blank taser (38. stunners too) shots no longer knocking people unconcious people for around 3 seconds. If the intent was to push crew members to using weapons outside of stun items, then halving the materials cost should accomplish the same thing.

The damage of .22's is halved if the target is wearing a armour vest and (quoting something Katzen said on the Discord), the bullets have fall off after 5 tiles making them even weaker. The current meta for combat is usually found in the ChemDispenser and TTV's. Making .22 magazines more accesible would ideally make people change that up.
