Missing hardcoded refmap file in common mixins for NeoForge release #90
Description
refmap file reference is hardcoded into the mixin json file but no refmap file is provided (in NeoForge release).
If a refmap is not required, and the chosen toolchain doesn't handle dynamic refmap entries, and it is still desirable to hardcode for the unnecessary refmap, then an empty refmap should be provided when refmaps are not needed.
