0.2.27

• Fixed a bug in Task.responsible attribute. This change has also slightly changed how the Task.responsible attribute works. It still comes from the parent if the Task.responsible is empty or None, but when queried it causes the attribute to be filled with parent data. This is a slight change, but may break some workflows.

• Added ScheduleMixin.to_unit that converts the given seconds to the given unit in consideration of the given schedule_model.
