[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.
