A more useful committer score card

Now with aliases for anyone who hit the top 20 list of the last year,
six months, and twelve weeks.

Still needs some optparsey niceities, but it's good enough for an
intial push to GitHub.

+# The commit_scorecard is a way to tell who's been active over the last
+# given period. It's of course, quite coarse -- someone with 10 commits in a day
+# may or may not be more productive than someone with 3, but over long enough
+# periods, it's an okay metric to measure involvement with the project, since
+# large and small commits will tend to average out.
+#
+# Note that this includes merge commits by default (which usually means at least
+# code review happened, so it's still a measure of work). You can get different
+# stats by ignoring merge commits, once option parsing is implemented.
