Warden: immune to projectiles shot from outside its sonic boom range

Players could kill the Warden with arrows from a hole or a tower where it
cannot reach them. WardenRangedImmunity cancels projectile damage to the
Warden (arrows, tridents, Dungeons Gear bolts...) when the shooter is
outside the sonic boom range (15 blocks horizontally, 20 vertically, as
in Warden#SonicBoom) or unknown (dispensers). Inside that range it can
still be shot, since it can answer with the sonic boom. The projectile
bounces off and the player gets an action bar message (es_es / en_us).
