Remove Config related methods in SongodaPlugin

Escept for #getExtraConfigs which got renamed, the other methods are no longer required and have been removed.

Additionally the config methods defined by Bukkit's JavaPlugin class
have been overwritten with empty bodies.
This prevents the default behaviour trying to access stuff that's not there
or should not be considered a valid config to use.
