Added a per-save config file called DimDoorsWorld.cfg. Its corresponding class is DDWorldProperties. This class supports whitelisting and blacklisting dimensions for Rift Cluster and Rift Gateway generation. Note that our ban against generating gateways in the Nether and The End still applies regardless of those settings. The new config file is loaded before the server starts initializing terrain. Also moved DDProperties to another package alongside DDWorldProperties - that required updating references in most of the mod's files.
