Java Edition 12w21b

12w21b was released to fix some of the bugs and crashes in the 12w21a snapshot.

Changes

 * New inventory screen in Creative mode.
 * Blocks and items are sorted by category, each category in its own tab. The categories are: Building Blocks, Decoration Blocks, Redstone, Transportation, Miscellaneous, Foodstuffs, Tools, Combat, Brewing, Materials
 * The inventory can be searched for specific items: just start typing while in the inventory screen. The search results will be displayed in the Search Items tab.
 * The player's survival mode inventory is accessible via a tab with the chest as its icon.
 * Brewed potions will not be included in their own category.
 * To close the new inventory window you must press 'Esc'. Using the default inventory key does not currently work.
 * Added monster egg (Silverfish blocks) to Creative inventory.
 * Saving and loading chunks is slightly faster.
 * Chainmail armor is now available in-game.
 * The F3 menu no longer has the graphs.
