Add i18n to QtShark

The goal is only to translate the Gui (Not dissector)
Actually, there is only a french translation.

To try, (if you are not French) launch qtshark with LANG=fr ./qtshark (in ui/qt folder)

Missing some feature :
* Add preference to select (force) your language
* Some Gui Text, it no available for translation
* Documentation about how to translate (Coming soon...)
* Your translation !
