The Language icon is not useful on user pages as most probably there
are no translated user pages, thus there is no need to show all-time

If overflow menu is available, don't show Language switcher icon in
toolbar, show it as first item in the overflow menu.

cluttering the Menu/ directory. Move the entries to a new subfolder.
