Make *.save files openable by sphereFACE as recognised by operating system

[Edward Hart-Davis]

I have no clue how it works, but it would be neat to be able to download someone else's save, have the game open, ask me whether I want to keep my current save, and have it either move my old save to a new file or just overwrite it, with the newly-imported save.

sphereFACE is only designed to open games on startup; anything else would just be adding obscure facilities that would at best facilitate savescumming only, and at worst interfere with the genuine operations of other software that wants to claim the .save extension. Plus would need a lot of platform-dependent code for something that's really a trivial vanity feature - not worth the work.
