title: :wrapper_tag, :wrapper_class options (and more) with simple_form and Rails 2.3?
body: <p>I'm making my first Rails project and I'm using the simple_form gem (version 1.0) with a Rails app (version 2.3.5).
  <a href="http://github.com/plataformatec/simple_form/tree/v1.0" rel="nofollow noreferrer">simple_form repository v=1.0</a></p>
  
  <p>Is there any way to implement the nice options :wrapper_tag, :wrapper_class, :wrapper_error_class ? Or maybe I'm missing something? :-D</p>
  
  <p>Thank you for your advices</p>
  
  <p>Fro_oo</p>
  
  <p>ps : I can't change my Rails gem and upgrade to a 3.x version...</p>
