wallpapers/slideshow: Allow setting global shortcut for next image action
- wallpapers/slideshow: Allow setting global shortcut for next image action
Moves the action to the backend plugin so it can talk to KGlobalAccel. Can be handy to have a shortcut rather than having to use the menu every time.
Reason for the change
see commit
Test plan
Assigned a global shortcut through the KCM, pressed it, wallpaper changed. No shortcut is assigned by default.
