Natural sort order

[WJTrevino]

Can the option to sort with "natural" ordering be added so titles like 2.10 can be sorted below 2.2? This could be minimally invasive by adding an nsort option which would use strnatcmp instead of strcmp.

$fnc = create_function('$a, $b', 'return strnatcmp(noNS($a["id"]), noNS($b["id"])); ');

sortby=title will sort by title which uses natural sorting with collator(=with support of sorting in the language of your wiki).
