Welcome to Meltron's wall of text!
Basically a lot of commands you won't even need 
Also I have not even figured out how to get the different block types X/ But red does not recommend spawning blocks and stuff directly, so use all these commands carefully! (= don't blame me if something goes wrong). But I have found some unused Items you can spawn 
This list is also not really sorted, so use [Ctrl] + [F] to search for an object quickly. Might update this at some time
