------------------

-[!] Clean up memory API
-	[!] Use double hashing instead of linear probing
-	[!] Store block info inside the block, not as a separate block
-		- This makes it too easy to clobber the memory information. By
-		  making it a separate block, there's less of a chance of the
-		  information getting destroyed. It's worth a few extra bytes of
-		  memory to make accidents harder, I think.
 [x] Add recipe to td script to upload patches to the Matrix room
