bawhoppen 7830992c11 Makes shuttles superficially buildable (#18974) 
Added two new materials, Titanium and plastitanium. Titanium is naturally occuring, and plastitanium is an alloy made of plasma and titanium.
These materials can be used to build shuttle walls and floors, though this serves no current purpose.

Before you yell "SNOWFLAKE" about the materials, I have definite planned purposes for them, not to mention what else they could be potentially used for (mechs, R&D, etc.)
You can use titanium to make white shuttle walls that smooth (like the ones of the escape shuttle), and plastitanium to make the grey syndie shuttle walls. You can also make floor tiles out of each material for the different shuttle floors. This PR itself doesn't change any of the paths on the map to use smoothed shuttlewalls and I'll save that for a seperate PR.

Also this PR makes ORM code better and allows people to easily add new alloys

/*
This datum should be used for handling mineral contents of machines and whatever else is supposed to hold minerals and make use of them.
Variables:
amount - raw amount of the mineral this container is holding, calculated by the defined value MINERAL_MATERIAL_AMOUNT=2000.
max_amount - max raw amount of mineral this container can hold.
sheet_type - type of the mineral sheet the container handles, used for output.
owner - object that this container is being used by, used for output.
MAX_STACK_SIZE - size of a stack of mineral sheets. Constant.
