/** 
 *         Form validator
 *        (c) 2004 NEGESO
 *    Changed by Yuri Shanoilo
 *
 * 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" onSubmit="return validate(this)">
 * <input type="text" required="true">
 * <fieldset required="true"><input type="checkbox"><input type="checkbox"></fieldset>
 * <input type="submit">
 * </form>
