[web/view/treeview] add a 'selected' class on <li> if the entity's url is the currently displayed url
An alternative would be to refactor the corresponding view so that controlling
css classes wouldn't require overriding a 5O-lines method.
Notice by default there is no associated class in the CSS so there is no
rendering difference unless one explicitly add rule in his CSS file.
for eschema in schema.entities():
if not (eschema.final or 'cw_source' in eschema.subjrels):
add_relation_definition(eschema.type, 'cw_source', 'CWSource', ask_confirm=False)
sql('INSERT INTO cw_source_relation(eid_from, eid_to) '
'SELECT e.eid,s.cw_eid FROM entities as e, cw_CWSource as s '
'WHERE s.cw_name=e.source AND NOT EXISTS(SELECT 1 FROM cw_source_relation WHERE eid_from=e.eid AND eid_to=s.cw_eid)')
