Array:sort(f) requires a sort function to be given

[mkottman]

Array:sort(f) in its current form requires a function to be given as the argument. When a simple comparison based on the < operator is sufficient, table.sort allows you to pass nil as the sort function to use the default sort order.

The following change allows you to use Array:sort() without an argument to use the default sort order, which is enough to sort arrays of strings and numbers.

Thanks, Michal. These little details matter!
