Have taken advantage of the 2.1 version to review every EN and FR languages files since 4859/4860 revisions (last commit on languages files by tosca).

Fixed typos and languages mistakes, and made EN and FR files consistent with one another.

Older languages files (prior to 4859 revision) still to be reviewed.
