Filter Save Files by Current or Backup

[TwoHeadedBoy]

The latest version of the Valheim client generates a ton of character backups and while I'm sure I can just trim them myself, I think it'd be handy if the editor could parse out backup saves vs current saves. I end up scrolling through a ton of backup .fch files trying to get to, for example, a second character save.

I have a fix for that quite soon, that I will create a PR for. A simple checkbox that filter out any backup versions of character files.
