Various README.md files updated

Mostly formatting fixes but some typos were fixed as well. This commit
is being made now so I can roll back
ad04d21fda as it seems to have been a
mistake to do. Another way to more easily identify same authors will
have to be figured out, perhaps in future files that are yet to be
generated. This upcoming commit will hopefully not cause any problems
but if there are any they will be worked out.

Landon and I both came to the same conclusion that although the renaming
directories seemed to have been warranted in theory they shouldn't have
been renamed after all. This was briefly discussed in issue #3. Anyway
this is why different years are in this commit: to get them out of the
way and since they're only README.md files this seems okay to do.
