TODO

   1 Sure :
   2  - translations
   3  - add defensive checks at many places to avoid ugly error screens (duplicate key, ...etc)
   4  - (re)factor some controllers code
   5
   6 Maybe :
   7  - redirect after page access http://knplabs.com/blog/2012/01/13/redirect-after-registration-in-symfony2/
   8  - move assets to bundles instead of web/mixstore
