nsm_all_del_quick: check for /etc/nsm/servertab and /etc/nsm/sensortab before 
trying to read

This checks for the existence of the files, alerts/exits if they are missing:

/usr/bin/nsm_all_del_quick

# Delete all sensors
if [ -f "/etc/nsm/sensortab" ];
  then for INTERFACE in `cat "/etc/nsm/sensortab" | grep -v "^#" |cut -f1`
    do
     echo y | nsm_sensor_del --sensor-name="$INTERFACE"
    done
  else echo "Sensortab appears to be missing! No sensors changed.";
fi

# Delete all servers (should only be one)
if [ -f "/etc/nsm/servertab" ];
  then for SERVER in `cat "/etc/nsm/servertab" | grep -v "^#" |cut -f1`
      do
        echo y | nsm_server_del --server-name="$SERVER"
      done
  else echo "Servertab appears to be missing! No servers changed.";
fi

Tested on:
Ubuntu 12.04.5 LTS
PPA packages

Tested against dummy files and NOT calling nsm_server/sensor_del.

Hope this helps.

Thanks, Tim!  I also added a check to ensure root privileges.
