Scavenger

• Add support for xInventories.
• Add new commands: scvrdisable & scvrenable.
• Add SingleItemKeeps option.
• Remove SingleItemDropsOnly option. See caveats.
• Add WorldGuard 6.0 support. Older versions excluded.
• Add support for Minigames 1.7.
• Ignore bad ItemStacks.
• Better handling of serialization errors.

NOTE: This update changes the way single item drops and keeps are handled. Please use scavenger.drop.[ITEM] to explicitly drop items when SingleItemDrops is true. To explicitly keep items use scavenger.keep.[ITEM] with SingleItemKeeps set to true. If you use SlotBasedRecovery with SingleItemKeeps the two checks will be an OR. To change this from OR to AND set UseTheOrMethod to false.
