Schematic rework (less, and consumable)

[Hotspot]

Hi! Current shcematics are not part of economic. also bit cliunky system.
My idea is to remove all shcematics except for final items (it's very big list of them)
t1 shcematics -- can be bought from bots, and infinite
>=t2 item shcematics -- make them consumable. Remove bot sellers, and place them into cargo of ship wrecks
