swimming speed of players at all (NoCheatPlus knows when players sprint,
use Swiftness potions etc and will already adapt the speed based on
that data).
maxcooldown:
How much time the player can spend in the air if his velocity has been
modified by an external plugin (PreciousStones for example). The default
delay is 10 seconds because it sounds like a player won't spend more
than 10 seconds in the air.
allowfastsneaking:
Should sneaking players be allowed to move as fast as normal players.
