Prior to this comment, the every-1d cron.py command was broken due
to lack of proper stats import. However, while refactoring this, it
was convenient to move other recurring tasks that had been stuffed in
odd places--not least `stats(...)`--into the new cron system. This
entailed a number of refactorings of other things.
1. Move stats(...) from static.py to helpers/stats.py.
2. Move hole inactivity purge task from stats(...) to routes/subs.py.
3. Move bot award timer checks from stats(...) to helpers/awards.py.
4. Unify award timer logic formerly in routes/front.py into the new
helpers/awards.py.
