Made the clan object interfaceable for loading custom clan objects
Clans Banks will only work with default clan implementations as of right now (on purpose for meta purposes)
Added two new managers (ShieldManager, ClanManager)
Cleaned up multiple events with un-necessary code
Removed clan duplication problem with creation of new clans (probably has to do with alot of peoples random issues with the plugin and will never persist again)
Migrated clan building objects to the api package.
Fixed 2 mistranslated messages previously resulting in just '{0}'
Now safely introducing player heads again within the GUI
Fixed automatic configuration update problems. (When you update the plugin this time your configs should all update correctly!)
