/** 
 *         Form validator
 *        (c) 2007 NEGESO
 *    Changed by Rostislav Brizgunov
 *
 * In all forms which should be validated
 * please add onSubmit="return validate(this)"
 * all forms with class="contact". Please
 * insert required="true" attribute-value pair
 * into such validated objects:
 * - required text field;
 * - fieldset, in which at least one checkbox
 *   should be checked.
 * 
 * 
 * Example:
 * <form class="contact">
 *     <input type="text" required="true">
 *     <fieldset required="true">
 *         <input type="checkbox">
 *         <input type="checkbox">
 *     </fieldset>
 *     <input type="submit" onclick="if (!validate(this.form)) return false;">
 * </form>
