From: skotlex <skotlex@54d463be-8e91-2dee-dedb-b68131a5f0ec>
Date: Wed, 31 May 2006 03:41:58 +0000
Subject: - Added function pc_check_skilltree for checking if you unlocked new
 tree-skills when raising non-passive skills. - Some cleaning of
 pc_calc_skilltree - Fixed flee/hit calculation in status_calc_bl to account
 for bonuses from the base status. - Some cleaning of status_calc_pet to use
 the cap_value define.
