:D

Adds a normalized name field to the user record. Also uses
normalized names conflicts to deny new user names.

Pensez à modifier ça dans votre config.py local pour tester, et à 
désindexer le fichier (pour pas commit l'inverse par mégarde)

Ajout d'un CoC Don't Be An Asshole.

- Ajout d'un modificateur pour changer les feuilles de style à la volée

Dans User.valid_name, ajout de caractères non autorisés. Voir #19 pour
faire quelque chose de vraiment propre et safe.
Dans privs, j'ai shooté des règles en double. Répercussion sur les
autres routes.
Ajout du champ username dans le formulaire admin de modif d'un compte.

The groups-privileges page takes care of removing privileges
before deleting groups and users; this is to be moved soon to a
proper group/user deletion API.

The News menu would not open when the user is authenticated,
leaving an empty menu area. Instead, the third button (Forum)
would open the News menu, shifthing every menu down a button.

This was caused by a bad selection query when getting the list
of menus; essentially the selection was equivalent to "#menu div".
Authenticated users have a div in the Account menu with their
name, so this div was mistaken for the second menu.

The problem was fixed by using a different selection equivalent
to "#menu > div" to get the list of menus.

This includes loading the common style sheets at low resolutions
and removing the undescribable redundancy in light.css.

The harder part was getting the navbar right, because it relied
heavily on the distinction between navbar.css and light.css.

This is still a work in progress.

Also more titles and details on other pages of
the administration section.
