Fork of Infinite Resources by sonaxaton, updated for Factorio 2.1.

Makes all resources infinite and not deplete, so their yield will never change. If a resource is not normally infinite, this mod will make it infinite and have 100% yield. Resources that are already infinite (like oil or some added by other mods) and have other yield settings are unchanged (except for making it so they don't deplete), so they may spawn with yields above or below 100%. But once spawned, no resource should deplete from mining. Also, whenever a resource is spawned, its yield is set to exactly its normal amount (for previously non-infinite resources, this is 100%), regardless of what yield it was given when the ore patch was generated.
