Prevent using enderpearls

[Axer22]

My suggestion is to add flag which can prevent from using enderpearls on field without disabling teleporting (prevent-teleport).

Could be named prevent-teleport-enderpearl (?

Hey, after some research I did, there is a flag called no-projectile-throw, which will basicly prevent players non alllowed in your field from throwing projectiles.

This though doesnt prevent it if the enderpearl was thrown outside your field, I will add a check to prevent that! Thanks :D
