 System Overview
 Enables a bounty hunter system on your server. When a player is killed by another player they will get a bounty gump asking them if they want to place a reward on the killers head. Once a player has a bounty on their head they will appear on the global bounty boards. A bounty will stay active for 30 days after 30 days if the bounty is not collected the bounty will expire and be removed from the global bounty boards. If a player with a current bounty commits another murder and gets another bounty placed on them that gold total with stack with the current bounty and the bounty expire time will reset.
