Example of usage:

Also it's nice to look at `hg stats -f "%H"` - displays graph of
activity during day. :-)

I'm not sure that I've chosen right way for grouping by user (it is
generalised in template parsing instead of being hard-coded like in
churn now), because templates are not usable now for grouping by
anything else. I can't invent anything except date, which is not very
usable without date formatting, so I've added another parameter for
that. At least there is almost no difference in running time:

=====
piranha at gtv ~/dev/hg/hg>hg stats -l
...
hg stats -l  61.54s user 0.92s system 99% cpu 1:02.50 total


piranha at gtv ~/dev/hg/hg>hg churn # this is old churn, before my patch
...
hg churn  61.02s user 0.82s system 99% cpu 1:01.85 total
