In the navigation menu's version selector, display versions in descending natural order

Currently, the navigation menu's version selector is displaying the list of versions in descending order of creation.

This can get tricky when looking for a version in a large list.

As version names are most often numbered, it would be interesting to see the higher version first. A descending alphabetical sorting would improve the situation, but a descending natural sorting would be better (11.0 being displayed before 2.0).
