[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.
if 'same_as' in schema:
sync_schema_props_perms('same_as', syncperms=False)
sync_schema_props_perms('Bookmark', syncperms=False)
