************************* [Fighter Custom AI] **********************************
    This is a custom AI file for fighters.

    This will either attack the imputted target, or attack the nearest seen
    or heard enemy. It will also attempt to use a random potion, or heal itself
    at 50% HP.
************************* [History] ********************************************
    1.3 - Added as sample
************************* [Workings] *******************************************
    Uses Combat_GetAITargetObject, to see if we saw something new or something.

    Then we do:

    - Healing (at 50%) using best
    - Potions (using random % below)
    - Attack in melee if under RANGE_FOR_MELEE, else attack at range
