Sort_by slug / path

My use-case is pretty straightforward and seems quite common to me. I have a number of pages and sections that start with a number prefix e.g., 00_post.md, 01_post.md, etc., and I’d like to have them sorted by this prefix. They don’t have this number in a title, so sorting by title is not an option. The only way is to sort by weight, which requires adding it to every single page.

The default sorting (none) seems to sort entities in random order, which makes no sense to me.

I can add a new sorting order: sort_by = slug or path, whichever seems more reasonable to you.

Let me know what you think, so I can start working on it.
