v0.5.0

Adds minute schedules

You now have the option to add a Minutes type schedule with a variable minutes parameter:

schedule('math.hypot',
        3, 4,
        schedule_type=Schedule.MINUTES,
        minutes = 5

The minutes field is also available in the Admin and is ignored by everything but the Minutes schedule type.

_Warning_
Please run migrations with python manage.py migrate after this update to add the new minutes field to the database.
