Clickable match fields
======================

Users can now click at the match string of a movement. Clicking it
will open a table with all movements having that match.

To implement this, I added a new virtual field
:attr:`lino_cosi.lib.ledger.model.Movement.match_link` which uses the
new table :class:`lino_cosi.lib.ledger.ui.MovementsByMatch`.

This table was the first example of a slave table whose master is a
simple string.  This usage was not yet supported and required some
minor changes to the framework (ticket:`681`).

Hamza, note that this change includes another little code change in
:mod:`lino.modlib.extjs.ext_renderer` which you should port to the
extjs6 renderer::
