* [ADD] website_shift: Super Coop info

Add a button to show email and phone of the super cooperator of a shift.

* [IMP] website_shift: Next shifts regular worker

Add configuration to specify how many next shifts for regular worker
must be shown to them on their personal web page. This config is called
`regular_next_shift_limit`.

Improve the view that shows the next shifts on the personal page for a
regular worker regarding to the `regular_next_shift_limit`.

Because all the next shifts are not created in the database, we need to
create 'fictive' one that are not stored.

Fix the case when an irregular worker that doesn't have write access to
beesdoo.shift.shift try to subscribe to a shift and got a 403 error.

* [FIX] website_theme: Theme must be an application

As wrote in this document :
https://www.odoo.com/documentation/9.0/howtos/themes.html#create-a-theme-module
a theme module must be an application.

* [FIX] webs_shift: Wrong display of date last shift

Fix the case when an irregular worker is in alert and that the date
before last shift is displayed.

The `date_before_last_shift` is renamed in `future_alert_start_time`.
This name better represent what this variable contains. It also explains
why this information does not have to be displayed when the worker is
already in alert mode as this date is the date in the future on which
the worker will be in alert.

* [FIX] website_shift: Co-operator -> Cooperator

* [FIX] website_shift: Past shifts not ordered desc

The past shift was not properly ordered. This fix by ordering the past
shifts from the newest to the oldest.

* [FIX] website_shift: Holiday shown after end of it

Before:
    The holiday is shown even if the holiday is in the past.
After:
    The holiday is shown only if the holiday is now or in the future.
