wallpaper: the engine's settings page

A page for the wallpaper engine: the on switch, the interval in
minutes, a Next button, and each screen's hearted list with a remove
control and a dim for files the gallery's scan did not find. The module
reads WallEngine.on itself, because a singleton is built on first use
and the timer has to run from session start, page opened or not.
