Renaming mcmod.info back
Fixing the mcmod.info issue.
Bumping the version up to 2.1.1.

Changes from 2.1.0:
- Nothing major, just updating the version of Forge and fixing the
mcmod.info file.
- With the above changes, I was able to successfully load a 1.6.4 save
with a Patchwork Flesh item that was there before.
