Upcoming with Pre-Release 3

The new version 1.3.0 will introduce a config file for activating/deactivating features and to control e.g. the health or damage of several entities added by this mod. A first version of the config is already in this release, but won't be used by the mod. These funtions will be enrolled with next beta versions.

Thanks to everyone for reporting issues and giving suggestions on the mod! I really appreciate that and I try my best to continue the development of this amazing project. Thank you! ♥
