wrong device name because of have a minus in the domain name

I have a minus (-) in my domainname for that the m2p names are shown wrong

My first solution is to change the regex at /opt/max2play/list_devices.sh

from
OUTPUT=nmap -R -p 80 –open $SUBNET.* | grep -o -e „\([a-zA-Z0-9\.]\+ ([0-9\.]\+)\)\|\([0-9\.]\{6,\}\)$“ | sed ’s/ (/|/;s/)//‘

to
OUTPUT=nmap -R -p 80 –open $SUBNET.* | grep -o -e „\([a-zA-Z0-9\.\-]\+ ([0-9\.]\+)\)\|\([0-9\.]\{6,\}\)$“ | sed ’s/ (/|/;s/)//‘

maybe you can change it at your code, better would be to use the first devicename until the first dot (.)
