Passage à Haml 6+

La nouvelle version supprime quelques helper, dont `list_of` qui était
utilisée ici et là et qui est maintenant rajoutée dans
`application_helper`.

Méthodes supprimées:
  block_is_haml?, capture_haml, escape_once, find_and_preserve, flatten, haml_concat,
  haml_indent, haml_tag, haml_tag_if, html_attrs, html_escape, init_haml_helpers, is_haml?,
  list_of, non_haml, precede, succeed, surround, tab_down, tab_up, with_tabs
