Openrct2: Move autosaves to a subfolder of /save

[Gymnasiast]

When attempting to load a game the list is a bit littered due to the autosaves. It would be nice to have them in a subfolder of /save, so they're still easily accessible in case they're needed. (This is also how OpenTTD does it.)

Someone proposed to simply have a horizontal bar separating autosaves from the user-made ones, but I think perhaps the subdirectory is a better option.

I would prefer an horizontal bar. It is a bit annoying to always have to go inside the folder prior to loading an auto save.

[Richard-L]

I agree it's necessary to separate autosaves somehow.

[Ryder17z]

Preferably there would be a setting for this in the config file. I'd vote for autosaves in a subfolder as the default though

[Stevoisiak]

I'll second the idea of a subfolder.
