    Stop translating icon name
    
    Gettext automatically extracts the icon name from the desktop file for
    translation¹ because it is a locale string in the desktop entry
    specification.² However we don’t want it translated. As it’s not
    possible to specify per-language keywords to stop xgettext from
    extracting the string use sed to remove it from the pot file.
