[evolution/webkit] Bug 644310 - Rework "Set as Background" image option

[Dan VrÃtil <dvratil src gnome org>]

    Bug 644310 - Rework "Set as Background" image option
    
    This adds a dependency on gsettings-desktop-schemas >= 2.91.92.
    The version was chosen for the change from "picture-filename" to
    "picture-uri" in the "org.gnome.desktop.background" schema.
    
    Also, we now save the background image under ~/Pictures since the old
    directory (~/.gnome2/wallpapers) is presumed deprecated in GNOME 3.
