rich seeds

Now there are a lot of seeds, properly stolen from
http://ec2014.vul.fi/nomeresults.html. Later might add
skier results too.

Many fixes are applied, most minor, which were noticed once the
seeds were entered.

In addition, 'show' action for a user shows its races (runs actually)
and allows applying for a run from there (but not un-applying).
