add dura thread crafting

[Tasald]

/obj/item/book/granter/crafting_recipe/threads This craftin thing and the recpies with it. currently unobtainable in game far as I am aware.

Dunknow why since durathread bags are still craft-able, but i'd love to have more of that blue drip. Last time i was able to get stuff, it could make 'ok' light armor and a better belt for utilities things, dunknow what all the other stuff is stat wise. I just feel it would be nice to have some of the things instead of durathread literally being only used for the duffles and nothing else.
