Graph list not ordered properly

[mcmancini@…]

I created 15 graphs. On the graph list (visible when first opening the program), the graphs are listed as 1, 10, 11, ..., 15, 2, 3, &c. I believe the proper way to order the list would be in counting order, i.e. 1, 2, ..., 9, 10, 11, &c. Counting order is the way that Mac Finder orders items with similar names.

(In [37]) Graph list now sorts like the Mac Finder: case insensitive, numeric, width insensitive and forced ordering (fix #18). New and renamed graphs now appear in correct sorting order.
