Small hack in logEval() helper, as it seems that PHP's error_get_last()
sometimes returns true, rather than NULL or an assoc array as per the
PHP doc, even when there hasn't been an error.  So now check for 'true'
and treat that as if it were a NULL (no error).
Added #__ parsing to placeholder handling, as per request in forums
