reset history

There is about four weeks worth of history, the interesting parts of
which I've documented in `CONTRIBUTING.md`. I'm now throwing this
history away because there is a lot of messing with data files in there
that bloats the repo unnecessarily, and this is my last chance to get
rid of that bloat before other people start pulling it.
