Tech Origin update:

-Various item have had their tech origins updated or added to.
-Items that just use metal or glass have their materials origin lowered
-Items that use more advance materials have their materials tech origin raised to equal the uncommon material.

Engineering Tech research:
-Engineering tech origin, because Materials tech origin is just for being able to manipulate rare/ new materials for production.
-Engineering tech field focuses on various engineering items, and will increase in scale as time goes on.
-Various items (especially tools and mech parts) use the engineering tech origin.

Mining tools update:
- Drills can dig up sand.
- Plasma cutters can cut down walls and girders, and set fire to thermite, and be used in the reinforced wall deconstruction stages in place of the welder.
- Diamond drills can drill though walls, and girders, and can drill through the plating of reinforced walls.

Tech Origin changes and Circuit boards:
-If it requires a special material to make, it now have a materials origin equal to that special material. General glass circuit boards do not require materials research.
-Engineering research should be applied (reasonably) to the board if it is a machine, computers should stick to programing (even if the computer is related to an engineering field).
-Still a work in progress, as always.

Last update:
-Shovel sprite is back to being a digging shovel in style, a scooping shovel is terrible at digging. I should know, I've dug many holes in my days, and a scooping shovel is terrible, and a spade head is much better.
