What is this fixing or adding?

Use alphabetic rather than asciibetic sorting when ingesting files for generation (upper and lower case letters will be interspersed rather than upper case before lower case. This doesn't fully order names. It's unclear if that would make things easier or harder (having all seeds together from a single file may make them easier to find).

How was this tested?

Generated many seeds.
