Foreignkeys in Action Parameter Window 
--------------------------------------

Lino can now handle Foreignkey fields in Action Parameter Windows.

This feature wasn't yet implemented.

Worked on docstring of :class:`lino.core.actors.Actor`.

In class :class:`BaseLayout <lino.core.layouts.BaseLayout>` renamed `_actor` to `_datasource`.

Moved the :mod:`choicelists <lino.core.choicelists>` 
and :mod:`workflows <lino.core.workflows>` 
modules from 
:mod:`lino.utils`
to :mod:`lino.core`.


Workflow of calendar events
---------------------------

The :class:`lino_xl.lib.cal.AssignEvent` action is a first 
usage example of the new feature since the field `assign_to` is 
a ForeignKey to User.
