    icons: override get_items() in sprites.thor to return gnome icons
    
    In upstream DevDocs the static icons SCSS file was replaced with a
    Ruby template that automagically computes icon offsets in the sprites.
    
    Remove our statically generated icon sprites and replace them with a
    JSON file that maps docs to icon names. Then override the `get_icons()`
    method in `sprites.thor` to return the proper icons.
    
    This results in a lot of redundant icon sprites, but requires less
    manual work and makes all the other icon related styles function.
