Localise display names for well-known user directories
OS: macOS (10.11) and Windows
Os default folder names in home aren't localized. I have a German setup but the folders show up in English.
Update by Jehan: This is about the common folders such as
Music/, Documents/` which are not localized when displayed in GtkFileChooser* widgets, apparently both on Windows and macOs. I am not sure if they are localized on Linux, so I guess if they are not either, we should keep it as-is; yet if they are localized on Linux, it would be worth being consistent and do the same on other OSes.
