French Translations

Here is a french translations. Not all is perfect but it's correct french language. Some expression could be more contextualized.

Especially :
I translate "budy" by "interlocuteur" but it's a little bit more formal than "budy". I'm opened to any suggestion.
Not convinced by my translation of "type" in "Type to filter" (line 760)
Missing translation for line 316 : "Refresh encrypted conversation"
