Due to the massive number of blocks, it would probably be a very good idea to look into automatic ID assignments right about now, and get rid of the ugly giant if block statement in world.py that just serves to preserve 1.12 compatibility.

Would it be worth forking 1.12 and back to it's own branch and then moving forward with better code for handling this? It's not like 1.12 is going to be getting any new features and this way, the code can be cleaned up a little without legacy support needing to be in place. Just my 2 cents
