[i18n]> update translations files for 1.1.2

First push for v.1.1.2 from TX to GH.

It's more a first go to make it clear for everybody.
So all translations aren't fully completed (but will be shortly) BUT are up to date with @pross last pot file.

For now to make it clear:

The pot is here and shouldn't be remove cause the file is used for the auto-update feature over TX.

@pross will be in charge of managing it here.

@djio @erwanlescot we only push from TX the po files (for the js translations) and create the mo files (for the php strings).

That's it
