serverFolderNameMode changed from NAME_ONLY to IP_ONLY (see content of DistantHorizons.toml for explanation)
reason: when set to NAME_ONLY, every time the server is renamed on the client, DH won't find the corresponing LOD database anymore. This results in
1. The DH client is without LODs -> bad user experience
2. The DH client would download the LODs again, which results in duplicate files in Distant_Horizons_server_data. The LODs easily occupy multiple gigabytes by default and now there are duplicates of them! -> bad user experience
solution: when set to IP_ONLY, the DH client will identify corresponding LOD database by "IP Address", although it can also be a domain name. It's actually the content of the "Server Address" field in the servers.dat file
