- in admin/configuration, add new step with "sections" (general, comments,

default, upload, metadata, sessions)

- admin/configuration.php and its template have been higly simplificated by
  making things more generic : for example, for each configuration
  parameter, its name must correspond to the name we find in the config
  table and belongs to a section, in the lang array we find :

  - $lang['conf_<section>_<param>']
  - $lang['conf_<section>_<param>_info']
  - $lang['conf_<section>_<param>_error'] optionnaly

- more described message when connection to database server is impossible

- redefinitions of get_languages and get_templates functions

- deletion of configuration parameters : webmaster, session_keyword

- rename of configuration parameters :

  - default_lang => default_language
  - default_style => default_template
