Some corrections for watchdog help

[Spacedust]

There is a lot of language bugs out there:

$__information['watchdog_addform__pre'] = "<p>Settings:" .
   "<ul>" .
   "<li>Servicename - service identity</li>" .
   "<li>Watchdog activated - enable or disable Watchdog service monitoring</li>" .
   "<li>Port - service port number</li>" .
   "<li>Action - command required to restart service</li>" .
   "</ul></p>" .
   "<p><b>Note</b>: - usually 'Action'  to restart service is 'service XXX restart' or '/etc/init.d/XXX restart'.</p>";
