Minor French translation Problem

[Tarantin]

Hello,

The "Guiding" and "Navigation" features are both translated to "Navigation" which is lexically correct but pretty confusing for a new (french) user (in the settings main menu, the two sections have exactly the same name!").

The following french texts should be changed :
* In settings main menu, "Guiding" shoud be translated to "Guidage".
* When selecting actions for a POI, "(Des)Activate Guiding" should be translated to "(Des)Activer le guidage"

Thanks a lot.
