 * New "treasure" enchantment: Mending

Changes

 * Anvil repairing
 * Renaming an item does not increase the repair cost for a future repair/rename any more.
 * Boats
 * Now slightly faster than sprinting.
 * This makes them similar in speed to the old boats, though with less momentum.
 * Players can now items and  immediately after they stop rowing.
 * All types of boats are now craftable.
 * Due to, the dark oak boat cannot be crafted.
 * Brewing Stand
 * Requires blaze powder to be able to use
 * One piece of blaze powder allows for 30 ingredients to be brewed in the brewing stand (tag: ).
 * To be exact, it removes 1 from fuel (1 blaze powder = 30 fuel) every time the player puts an ingredient in (if the player takes it out and puts it back in, it takes another fuel).
 * Can be automated by putting a hopper feeding in the side of the block like water bottles.
 * Elytra
 * Nerfed - the player is no longer able to go higher than where they started.
 * New sneaking animation.
 * The player can now fit through one block high gaps while gliding.
 * Horizontal collisions now deal damage, new death message: "Player experienced kinetic energy".
 * Enchanting
 * Enchantments with max 1 level will no longer display the level, e.g. "Infinity" rather than "Infinity I".
 * When multiple pieces of Thorns armor are worn, one will now be chosen at random instead of always using the "bottommost" piece.
 * Players
 * When crouching, players are 1.65 blocks tall (versus 1.8 blocks normally).
 * When flying with elytra, players are now only 0.6 blocks tall.
 * When laying in bed, players are as tall as a 0.2 blocks cube
 * Splash text
 * Changed "0% sugar" to "1% sugar".
