Auto Wallpaper switch for only Main or Lock screen

[weiss1597]

An ideia for enhancement
Add a "toggle" switch on auto wallpapers for updating only Main "home" wallpaper or only Lock screen wallpaper, default being the actual behavior of updating both.

Similar to #14 suggestion about different controls for main and lock screen, but in this case not necessarily having different folders for each, would be nice having that ye, but say a "simple" toggle to stop your Lock Screen wallpaper from changing would be great!

as for a reason why having that added would be good, it's simply for privacy, say some stranger pick up your phone all he would be able to see on a locked phone is your Lock Screen wallpaper, no more than that, and maybe you don't feel comfortable having some possible weirdo seeing your private Shrek pictures you wanted to use as your Main Wallpaper
