theme: Remove COLORIZE feature of images
From a quick code search and grep of gnome-themes-standard, none of the themes that I inspected used this feature. Since it's the last thing that uses a lot of old legacy GdkPixbuf code, I'd rather just consider the feature unsupported at this point and clean up everything I need to. https://bugzilla.gnome.org/show_bug.cgi?id=662962
