Some fine-tuning in :mod:`lino_welfare.modlib.reception`.

Renamed `CreateEventActionsByClient` to
:class:`lino_welfare.modlib.reception.models.FindDateByClientTable
<FindDateByClientTable>`.  Moved `ButtonsTable` to
:class:`lino.core.tables.ButtonsTable`.

We had the following ordering of buttons on pcsw.Client:
:guilabel:`Find date with`, :guilabel:`Read eID card`,
:guilabel:`Create promt event`.  The button for :guilabel:`Read eID
card` was "at the wrong place": it must be either *before* or *after*
the two other actions.  This was because :class:`ShowSlaveTable
<lino.core.actions.ShowSlaveTable>` did not yet (as it should) copy
over the :attr:`sort_index <lino.core.actors.Actor.sort_index>`
specified on the table to the :attr:`sort_index
<lino.core.actions.Action.sort_index>`.  of the action.  Yet another
bug in the framework fixed!

The list of users to display in `FindDateByClientTable` must not
include `watch_tim`.  The selection criteria is now centralized in a
function :func:`appointable_users
<lino_welfare.modlib.reception.models.appointable_users>`.

Note that we cannot currently make that list depend on the client's
:attr:`lino_welfare.modlib.pcsw.models.Client.client_state` or the
clerk's user profile. That's because choosers know neither the
requesting user nor the `master_instance` of the query.  A missing
feature which might be useful to implement some day: ticket
:ticket:`56`.


It is now possible to specify a `master_field` attribute to
:func:`lino.utils.sendchanges.register`.  Usage example::

    def do_site_startup(self):

        super(Site, self).do_site_startup()

        from lino.utils.sendchanges import subscribe, register
        
        register('pcsw.Client', 
                 'first_name last_name birth_date national_id',
                 'created_body.eml', 'updated_body.eml')

        from django.utils.translation import ugettext as _
        e = register('addresses.Address', 
                     'street city street_no street_box region',
                     master_field='partner')
        e.update_subject = _("Updated: {obj.address_type} of {master}")
