create .mailmap file (for git shortlog/blame)

Recently it was suggested on the list that we add a contributor to
AUTHORS. This file has been unmodified for 7 years, and is somewhat out
of date. It would potentially make sense to automagically update this
file during the release process using the output from git shortlog. This
file helps clean up some inconsistencies in author data in the history.
