  remain py2.6 stuff that can be delete
  Here :
  https://github.com/web2py/web2py/blob/0d646fa5e7c731cb5c392adf6a885351e77e4903/gluon/import_all.py#L86
  
  py26_deprecated is used before been declared...
  
  Since we drop py2.6 : https://groups.google.com/d/msg/web2py-developers/xz5o_CF4GOo/ZJm0HImTAAAJ
  
  Shall we delete those line??
  
  I send a PR if you take it...
