               Custom Design & Pre-Processor For Custom Fields
               ---------------------------------------------------------------------------------------------
               You can create a custom design for any CF, first use:
                    print_r ($v);

               You will see that cf structure consists of: cf_idx, cf_title, cf_value, cf_type & cf_raw

               Let say you have: short_text cf, with idx = cf_99, to create a custom design:

               The easiest:
               { after: // CF pre-process goes here, place }
                    if ($v['cf_idx'] == 'cf_99') $v['cf_value'] = do_something_with_cf ($v['cf_raw']);

               Advanced example:
               { after: // CF pre-process goes here, place }
                    if ($v['cf_idx'] == 'cf_99')
                        $item['my_cf_design'] = do_something_with_cf ($v['cf_raw']);
                    else
                        $item['block_cf_list'] .= quick_tpl ($tpl_block['cf_list'], $v);

               { in detail.tpl }
                    <p>Calling Name: {$my_cf_design}</p>
