Update translation_fr.ts

[Norde]

Partial update of translation_fr.ts :

• Almost all strings translated (except those that do not seem to require a translation. See below)
• Spelling / grammar correction
• Sentences construction correction
• Specific french punctuation correction

For future update, are these kind of strings intended to be translated?
ie :
<source>all&amp;usb</source> <translation type="unfinished"></translation>
<location filename="mainwindow.ui" line="474"/> <location filename="mainwindow.ui" line="660"/> <source>N</source>
<location filename="WidgetKeyboard.ui" line="112"/> <source>F2</source>

If not, is it better to leave the tag empty or fill it with the same string as the source?

The Internationalization will hopefully be improved in a future iteration to allow better translations.

The & instances indicate a shortcut key. I'm not sure if changing the shortcut key because of text language changes will work or not. Changing it also requires that the key is unique in a dialog box. To play safe, I would keep them the same.

Anything that has a translation type of "unfinished" really needs translating if possible. But if it is left empty, I think the English version will be used anyway.
Thanks for the update.

Thank you for the clarification.
In this case i will check the shortcuts keys and finish updating the translation.
