Subject: [PATCH] limit the range at which we'll consider an attackable target
This patch aims to ensure that MCP World#getNearestAttackablePlayer
will not trigger chunk loads due to PathfinderGoalNearestAttackableTarget
performing a ray trace operation by pre-checking the maximum limit;
Given that the implementation shows that the limit should only ever
decrease when set, allowing us to skip further checks earlier on
when looking for an attackable entity
