Fix all/most of the unknown items in craft recepies

Fixes most (Some seemed as if they didn't need fixing, I was worried about breaking things with others, and moreblocks is a law unto itself, so I left the errors found with that well alone!!) of the errors found by this: https://forum.minetest.net/viewtopic.php?id=5831

Everything seems to work alright, but I'm not sure if the darkage aliases work alright... They **should** work, but you may (probably should!) want to test it with a backup of your map before merging it...
