Fix TypeAhead on dijit.Dialog

/**
 * Fixes a type ahead control on a dialog box created manually using dijit.Dialog (not by extlib).
 * You should call this function after creating a dialog.
 * The TypeAhead control uses the TypeAheadReadStore to retrieve suggestions. 
 * When creating this object the url attribute is set to the action attribute of a form.
 * But when creating a dialog box it's created outside form (as the last element before the closing tag of BODY.
 * So for a dialog to work in XPages you should move it inside the FORM tag.
 * But when creating a TypeAhead store object inside a dialog box there is no form and the url is empty.
 * This function will iterate over all TypeAhead stores and fix the url attribute.
