WIP: Galène with multilingual capacity

[Mejans]

This is just for the index.html page but the bases are here for i18n
The same logic has to be done with galene.html and 404.html

Please include the licensing information for simple-translator. Perhaps it should go into its own subdirectory of scripts/?
Please provide a clean patch series (use "git rebase -i" and "squash").

Where's the part that internationalises messages that come from Javascript?

[Mejans]

Hello, it's not finished yet.
Will have to learn how to use "git rebase -i" and "squash". What JavaScript message?

[jech]

it's not finished yet.

Ah, ok. Please remove « WIP » from the subject when you feel it's ready to review.

What JavaScript message?

A number of messages are generated by the Javascript code. Look at the calls to « displayError », for example.
