Lifesteal: FairPlay Edition

This is a normal Lifesteal mod with heart transfer on player kills and a command to do it manually. It aims for fair play, as there is no crafting recipe for hearts, so that grinders can't ruin the playing experience for others. There is also no ban if you get killed with only one heart remaining, since this would also ruin the experience for many. In future versions, a config file may be added for full customization of features.
