Update French translation cr_strings.xml

Temasek,

Here you will find an updated 100% french translation for your Rom!

I hope it will be useful for you.
I don't know if I send you the correct format since its the first time I try to do that.
If you have any problem with that please tell me what can I do to improve my work!

Thanks again for your amazing rom and Im glad to be a very little contributor to your Rom!

Cheers men!!
