hr.schedule on_change date_start

[Mustafa Rawi]

In hr.schedule form, the field date_start has on_change value to update description (name) field. Selecting or typing in the field, updates description and clears date_start.

----------------------------------------
Update:
Looking through the code, I found the reason for this behavior. The onchange tries to make sure the selected start date is a Monday. Any other value returns false and clears the field.

For internationlization purposes, I suggest either to remove this constraint or allow setting 1st day of the week. Oman's week starts on Saturday and Egypt's starts on Sunday, just to name a few.

in hr_sechdule.py @ line 240:
            # The schedule must start on a Monday
            if dStart.weekday() != 0:
                res['value']['date_start'] = False
                res['value']['date_end'] = False
