From f0fa9794bcdde0b1402bb7a7256265f59bbd7313 Mon Sep 17 00:00:00 2001
From: skotlex <skotlex@54d463be-8e91-2dee-dedb-b68131a5f0ec>
Date: Thu, 6 Jul 2006 18:47:11 +0000
Subject: - Added EQP_/EQI_ constants in pc.h to identify equip position and
 equip indexes, makes equipping related code much easier to read. - Also
 cleaned up pc_equipitem. When dual wielding or equipping accessories, if the
 client actually specifies one of the two positions, it will be taken into
 account.
