I do intend to increase my commit count here as a contributor to pomf/pomf, so I will add myself to the git mailing map for that reason.

Although alchimist has not yet merged any commits to master as of this
commit, it is anticipated to happen eventually after he's done working
with his branches. Regardless, adding this makes sure git-shortlog(1)
will display the up-to-date email address.

Eliot has also contributed three commits with his name using
contact@pantsu.cat. The match on pantsucat name is too specific.

This groups those three commits to Eliot Whalan <ewahl@pantsu.cat>.

From git-shortlog(1) man page:

> The .mailmap feature is used to coalesce together commits by the same
> person in the shortlog, where their name and/or email address was
> spelled differently.
