[Cin] French translation update

[Phyllis Smith]

About the French translation update from Olivier.  It has been checked into
the Git repository.
@Pierre - there is a Mint18 build if you would like to check it out at:

https://www.cinelerra-gg.org/download/testing/cinelerra-5.1-mint18-x86_64-static.txz
and as usual it contains a bunch of other changes to include some masking
fixes (later I will update BT #2)

2. edited po/xlat.sh and added "--from-code utf-8" to the xgettext line
>
The above has been corrected xlat.sh as you provided and checked into GIT
just now.

> 4. ran: msgmerge -U po/fr.po po/cin.po

I have updated the documentation here locally in the manual Translations
chapter to recommend your method as being a lot simpler to follow.  And I
will update the cinelerra-gg website also because being a lot less
complicated may result in more language translations.  Thanks for all of
your help.  gg/Phyllis
