[uicfg] uicfg.py moves from web/ to web/views/ (prepares #2406609) We are about to make uicfg selectable. Registrable / selectable views and helpers live in web/views. Hence the move. Backward compat is put in place. However CubicWeb imports of uicfg are updated to the new location.

$(document).ready(function() {
    $('a.rhythm').click(function (event){

        $('div#page').toggleClass('rhythm_bg');
        event.preventDefault();
    });
});
