[PATCH v3 0/5] add git-contacts helper

This is v3 of the Perl rewrite of Felipe Contreras' git-related v9 patch series [1] which was written in Ruby. v2 of this series is here [2].

v3 adds git mailmap support and documentation. It requires check-mailmap [3] functionality (es/check-mailmap in 'pu'), though it does not otherwise depend upon it textually.

Patch 1/5: Same as v2 except that the variable holding the commit
    counts for each contact has been renamed and changed from a hash
    to a hash reference in order to simplify patch 4/5.

Patch 2/5: Same as v2.

Patch 3/5: Same as v2.

Patch 4/5: New. Add mailmap support.

Patch 5/5: New. Add documentation.

Possible future directions and considerations:

* Make participation parameters (minimum-percent, blame since-date,
  -C level) configurable.

* Optimize by enhancing git-blame to accept multiple -L's.
