GExperts Sort Selected Lines Expert now uses “natural” sort order

Achim Kalwa, who has been steadily contributing to GExperts, submitted a patch that changes the sort order used by the “Sort Selected Lines” Expert in GExperts to use the natural sort order, similar to the way Windows Explorer sorts files. E.g. Assume you want to sort the following:

  Label20
  Label1
  Label10
  Label2
  Label100
  Label3
  Label11

The old code sorted it like this:

  Label1
  Label10
  Label100
  Label11
  Label2
  Label20
  Label3

The new code does this:

  Label1
  Label2
  Label3
  Label10
  Label11
  Label20
  Label100

I have accepted this patch as is. Not sure whether there should be an option to switch between the new and the old sort order.
