Changing wallpaper changes config

[dablenparty]

This isn't exactly an "issue" but I can't see a discussion tab on this repo so I'm opening this issue.

Currently, when setting a wallpaper, waypaper saves the wallpaper state by setting the wallpaper key in ~/.config/waypaper/config.ini. I think it would be better to store this state in a separate file primarily because the wallpaper key is saved application state and thus, in my opinion, doesn't belong in the static config file. This would improve the separation of concerns because you would have a state file that gets updated whenever the wallpaper state updates and the config file wouldn't change at all.

Hi, actually it's already implemented, you can switch to this behavior by setting use_xdg_state = True in the config. Then state parameters will be saved in the state file.
