assuming 'backtrace'

hello

thanks for the plugin. There is one bug visible when you allow wp debug mode.

Notice: Use of undefined constant backtrace - assumed 'backtrace' in ..wp-content/plugins/wp-mail-log/wp-mail-log.php on line 16

Else I cannot complain so far.. the log is bit overwhelming for me.. let say too raw.

thanks anyway ??
