Copied simpleStairsUp and simpleStairsDown into the core schematics
folder. It's likely they'll be useful for testing in the future. To be
clear, I didn't remove them from the regular "ruins" folder, just copied
them.
Removed untagged schematics and replaced them with the tagged
schematics. Moved two schematics that said NOT DONE into a "wip"
subfolder. Moved somethingBroke into a "core" subfolder. All remaining
schematics were placed in a "ruins" subfolder in preparation for the new
dungeon packs system. I did my best to ensure that all of the old
schematics had been copied and tagged, but it's possible I might have
missed one or two. I also copied in my new dungeons. This commit
temporarily breaks the mod until the new file names and locations are
referenced.
