Website update

We will install a translation mechanism to be able to translate the website content.

If everything is done well, no perturbation would be seen and the website could be translatable on tonight.

The translated items will be (for the moment) :

- the info pages

- the documentation pages

- the main menu

For a recall, the users can change their langage from their profile on the website.

These modifications do not concern the grid inworld at all.
