Infamy for murder spreads and add a villager "Fence" to buy reputation

I would like to see a more detailed reputation system. 

• Murdering villagers is a horrible crime and hits you with -10 reputation.  (currently -2 is just too unrealistic).
• Remove the -30 bottom and make it endless....or at least much, much lower.
• Add a new villager called a Fence (i.e. black market) which will allow players to purchase reputation points for emeralds (this is needed if we eliminate the bottom threshold for reputation).  For example, 10 emeralds buys 1 reputation point in a particular village.
• Murdering an entire village is notorious action that will result in an instant  reputation hit in all villages in neighboring regions.
• Interacting with any fence will allow players to buy reputation points back for villages in that region and in neighboring regions.
