 function nocache_headers needs to be modified to not try to set/remove
 headers when the headers were already sent to avoid generating a notice.

 Optionally it would also make sense to change the return type to bool, so
 we can return false in case the headers were already sent.

 Suggestion (would be better with return false; though):

 {{{
 function nocache_headers() {
         if ( headers_sent() ) {
                 return;
         }
 }}}
