/**
 *
 * The gsom_put_form modification by Rene Reimann
 *   
 * @autor Rene Reimann Germany saxony-anhalt halle (saale)
 * @mail [email protected]  
 * 
 * The double opt-in form will only work  with activated JS.
 * So, unfortunately, the flexibility is restricted. The JS 
 * implementation creates a bloated html construct. 
 *
 * I adapted the "gsom_put_form" function so that it is now
 * possible to integrated the form  with or without JS.
 *
 * Here was the  "gsom_form_without_js"-hook involved. 
 * It ensures the integration of the form without JS. To increase 
 * the flexibility of the function I added some hooks.
 * 
 * This modification is localized in glsft-optin.php @ line 2749
