////////////////////////////////////////////////////////////////////////////////
 OnPlayerTarget event script
    Used to allow player targeting while passing any module player targeting
    script through to work as intended.

    We Use a string variable upon the player using the targeting mode to define the
    action of the target.
    AI_TARGET_MODE is the constant used.
    AI_TARGET_ASSOCIATE is the associate that triggered the target mode.

    AI_TARGET_MODE_ON defines if the player is in target mode for a henchman instead of the PC.
