Add .mailmap for use with git shortlog and friends

This mailmap file normalizes staff commit author metadata to reflect
preferred first and last name values and correct @gradle.com addresses
in the results of `git shortlog` (by default) and `git log`
(when `--use-mailmap` is provided).

Note that only commits made since the beginning of 2015 were considered
and included, in a best effort attempt to include only those staff who
would have been around to be assigned a @gradle.com address in the first
place.

For details, see the git shortlog manpage (`git shortlog --help`) and
search for "mailmap".
