portable home directories search paths

AppImage is excellent! new feature: please have the runtime also look for portable home directories with the short app name (such as the prefix or [Desktop Entry] Name=). for example.

Firefox.AppImage.home
Firefox.AppImage.config

having that allows keeping settings when auto upgrading app versions.

the logic can be to first search for portable home directories by filename (as you do now) and if not found then search by short app name (such as the prefix and/or "desktop-entry-name").

much appreciated. thanks.
