title: Symfony use_javascript() routing issue
body: <p>i am using symfony 1.4.11; use_helper('Url').</p>
  
  <p>On using link_to('new',course/course/type/new),
   the url it show is ../backend_dev/backend_dev/Course/course/type/new 
      instead of 
  ../backend_dev/Course/course/type/new.
  Same issue exist for form_tag also. </p>
  
  <p>Edit</p>
  
  <p>Above issue was solved.By setting no_script_name: true at config and clearing cache.</p>
  
  <p>But image_tag(),use_stylesheet() and use_javascript() gives path as for example</p>
  
  <blockquote>
    <p>use_javascript('jquery-1.6.1.min.js') 
     ==>../web/backend_dev/js/jquery-1.6.1.min.js</p>
  </blockquote>
  
  <p>instead of</p>
  
  <blockquote>
    <p>use_javascript('jquery-1.6.1.min.js') ==>../web/js/jquery-1.6.1.min.js</p>
  </blockquote>
  
  <p>Any help appreciated.</p>
