Changes to Flights Page

Flights Page: Added plot2.tpl so that when clicking the flight link, no markers can be seen

Notes:

1. acID and flID in div class sidebar left
2. Add below in flight.php (not flights.php):
   

           $dbh = $common->pdoOpen();
           $sql = "SELECT id, icao, firstSeen FROM ".$settings::db_prefix."aircraft WHERE id = :id";
           $sth = $dbh->prepare($sql);
           $sth->bindParam(':id', $position['aircraft'], PDO::PARAM_INT);
           $sth->execute();
           $aircraft = $sth->fetch();
           $sth = NULL;
           $dbh = NULL;

   
           $flightData['flId'] = $flight['id'];
           $flightData['acId'] = $aircraft['id'];
           $flightData['icao'] = $aircraft['icao'];
           $flightData['flight'] = $flight['flight'];
