git-fame v1.11.1 stable

• support aggregating multiple repositories (#24)
• re-fix under-counting loc (#28, #15)
• update documentation
• misc framework & test updates
  • fix PR builds (#33)

---

• .mailmap is respected per-repository to help with aggregating stats
• --branch (default: HEAD, i.e. current) is shared across all repos
  • will have to think about how to specify per-repo branches if there is enough demand for it
  • in the meantime, work-around is to checkout desired branches before running git-fame
• argopt/docopt/argparse don't seem to order options consistently, so now manpages are generated directly from the docstring
