These commands are to equip a equipment on the attached character.
The equip function will equip the item ID given when the player has
this item in his/her inventory, while the autoequip function will
equip the given item ID when this is looted. The option parameter of
the autoequip is 1 or 0, 1 to turn it on, and 0 to turn it off.

Example(s):

//This will equip a 1104 (falchion) on the character if this is in the inventory.
equip 1104;

//The invoked character will now automatically equip a falchion when it's looted.
autoequip 1104,1;

//The invoked character will no longer automatically equip a falchion.
autoequip 1104,0;
