Update PrivacyListManager
- to use CopyOnWriteArraySet for listeners - do not wrap instance map in sync block (getInstanceFor() is already synchronized) - use PacketTypeFilter instead of PacketExtensionFilter - add removeListener(PrivacyListListener) - rework getPrivacyLists - don't set from attribute - remove unused getUser()
