PK Reward Restrictions & Bug Fixes

• Players who die in PvP now receive a lock effect for 6-10 minutes. Players with this lock effect are not worth any rewards in PvP 
  therefore, when you die in PvP, nobody will gain rewards for killing you for a while. (You also cannot receive XP for dying in PvP until the lock fades.)
• Adjusted pk merit - player comparison is now stricter, further reducing or eliminating the amount of merit gained from smaller
  targets.
• New helpfile: help pk rewards.
• Removed morality restrictions from renown.
• Fixed a bug in which empyreal vigilance was not properly granting its projectile avoidance benefit.
