Sort globbed files for releases

This change simply sorts the list of files after the glob has been resolved. This is useful because these files are often destined for a release, and having to scroll through hundreds of files which aren't sorted is *painful*.

I'm happy to convert this into an option that can be specified in the yaml if you'd prefer?
