[PATCH 2/2] Remove angle brackets from {author,committer}_email

[john at keeping.me.uk (John Keeping)]

This matches the internal representation in libgit.a, so it will make it
much easier to use Git's mailmap code.

The change in ui-atom.c isn't strictly necessary since the code copes
with email addresses both with and without angle brackets, but it's a
nice simplification since we know that the email address will always be
provided in the correct form.
