French translation

[cool]

Hello all,

I translated the version 1.221 in French.

Hope you will enjoy !

it seems, you ignored old file from https://sourceforge.net/projects/cudate ... nslations/ , too many lines are changed.
can you only update old FR file, pls?
keep it's header-comments about old authors, add your name in header too.

see file 'data/lang/history.txt' for changes in FR file since 2023.05 - last version of existing FR file.
