program: add infrastructure for the progrank job (#114)

* Add an automatic job every day at 4 AM to recompute the progrank of
  every program. Currently everyone gets progrank 0.

[MIGRATION] This commit contains a new version of the schema.

[SETUP]
* Install flask-crontab (with pip)
* Run `flask crontab add` to register the jobs
