The changes are all related to the use of gendered or binary language in
the comments, messages, and documents (e.g. referring to the user explicitly
as "he" or "he/she").  I searched for thse instances and changed them to
the gender-neutral singular they (http://en.wikipedia.org/wiki/Singular_they).
In the process I fixed quite a few typos that would show up in the
auto-generated documentation.
