Added the material synthesizer, and commented out materials for MoMMIs.

- Takes RCD ammo for humans, and cell charge for MoMMIs
- Can scan new materials to make them, and starts off with metal, glass, rglass, and plasteel
- Rare materials are expensive to make, and the design itself is high-tech and costly for humans to avoid it being too exploitable

Changelog done.
A nice effect of this is that MoMMIs can now fill machines directly, instead of having to do stupid bypasses.
Which is nice.
