/**
 * @author gabizou - April 8th, 2016
 * @author gabizou - April 11th, 2016 - Update for 1.9 - This enitre method was rewritten
 *
 * @reason Rewrites the attackTargetEntityWithCurrentItem to throw an {@link AttackEntityEvent} prior
 * to the ensuing {@link DamageEntityEvent}. This should cover all cases where players are
 * attacking entities and those entities override {@link EntityLivingBase#attackEntityFrom(DamageSource, float)}
 * and effectively bypass our damage event hooks.
 *
 * LVT Rename Table:
 * float f        | damage               |
 * float f1       | enchantmentDamage    |
 * float f2       | attackStrength       |
 * boolean flag   | isStrongAttack       |
 * boolean flag1  | isSprintingAttack    |
 * boolean flag2  | isCriticalAttack     | Whether critical particles will spawn and of course, multiply the output damage
 * boolean flag3  | isSweapingAttack     | Whether the player is sweaping an attack and will deal AoE damage
 * int i          | knockbackModifier    | The knockback modifier, must be set from the event after it has been thrown
 * float f4       | targetOriginalHealth | This is initially set as the entity original health
 * boolean flag4  | litEntityOnFire      | This is an internal flag to where if the attack failed, the entity is no longer set on fire
 * int j          | fireAspectModifier   | Literally just to check that the weapon used has fire aspect enchantments
 * double d0      | distanceWalkedDelta  | This checks that the distance walked delta is more than the normal walking speed to evaluate if you're making a sweaping attack
 * double d1      | targetMotionX        | Current target entity motion x vector
 * double d2      | targetMotionY        | Current target entity motion y vector
 * double d3      | targetMotionZ        | Current target entity motion z vector
 * boolean flag5  | attackSucceeded      | Whether the attack event succeeded
 *
 * @param targetEntity The target entity
