Sounds

Added new sounds for sound events entity.player.hurt_drown and entity.player.hurt_on_fire.

Changes

Mobs

Parrots

Changed parrots to be tamed with seeds, not cookies.
- Attempting to feed a parrot a cookie instantly kills the parrot.
  - The parrot gives off Poison particles as it dies.
  - Displays the message "Parrot was slain by <player>".
Allowed parrots to spawn in old jungles.

Withers

Can no longer break end gateway blocks and piston extensions.

General

Functions

Commands on each line no longer begin with "/" (forwards slash).
Now only use "#" to comment (not "//").
Functions should recurse as expected, even while mixing /function and /execute.

Some optimizations to advancements.

Tutorial hints

Now smarter about deciding whether or not to display.
