Fixes 11/30

[Pro Noob]

• New drop system have been implemented.
  - It works as follow: Always drops + chance of 1 item from the not always drop table.
  - This allow us to edit drops on a whim. So if there is any ideas or issues around drops, we can fix it.

• Fixed a issue with not recieve loot if you are 5 or more squares away from the killing blow
• Fixed a issue with finding out who killed the npc (One example is the jungle demon)
• Ring of wealth no longer works on rune pouches drop rate
