fixes #2442 remove "Customize" and related strings from language files

Deleted the "Customize" and "customize the appareance of the gallery" translation strings from all language files. Added a new string for "edit user preferences" in en_UK and fr_FR. This streamlines user preference terminology and removes redundant or outdated translation keys.
