    svtools: encode Base64 the images of the items of the control "ValueSet"
    
    Unfortunately the "Table Design" panel has a "ValueSet" control with
    images constructed with the function "CreateDesignPreview". I have no
    other choice to export the images to base64 and send it to client.
    
    Perhaps later we can optimize the function "CreateDesignPreview", to
    accept SVG pattern or something related.
