Java What changed in 13w21a

Everything below is measured by comparing the game files of 13w19a with 13w21a — not copied from patch notes.

Minecraft did not ship a data generator until January 2018, so there is no registry of blocks and items to compare for a build this old. What is below is read from the game’s own client.jar: the text the game displays, and the textures, models and sounds it ships. New blocks and items almost always show up in both.
