Previously for `appointment`, now for `appointment_hr`, the computation of
users' availability for appointment slots can be dependent on that person's
work schedule if:
* The user is linked to an employee
* The user's employee has working hours defined (resource calendar)
This commit provides working hours to all employees and a user to some, within
a multi-company setup.
