Option to always sort autosaves to the bottom

[Melany]

Since 4.14.1 added a new way to sort saves, I was wondering if it would be possible to implement an option that would always sort autosaves to the bottom of the list? I like having a large amount of autosaves, but the downside is that I either have to scroll down past them all, or prefix all my regular saves with "AA" to force them to the top. Having autosaves always shoved to the bottom regardless of name would be very handy.

Alternatively I could make do with an option to change the autosave prefix, in which case I could just change it to "zsave" or something.
