[WIP] The -Lathe Update

Here's the idea in a nutshell:

- Nerf the fuck out of the autolathe, make it public access somewhere
- Autolathe will retain its simple list menu but only produce simple items from now on
- Add 'Heavy Lathe' utilizing old unused sprites:

- Heavy Lathe will have a queuing system, categories, and will be able to produce complex devices **IN ADDITION** to the normal autolathe items. Essentially, the old autolathe with all the nifty unique complex stuff that was gutted from the autolathe.
- Protolathe will adapt the same queuing system the heavy lathe has for the benefit of science as well in this update.
