Discovery changes and enhancements

[cybercop23]

1. Fixed warning issue with IPs being reversed
2. Detect and check if UUID has more than one interface that's actually pingable - remove the extra prompt if IP is from the ColorLight or show network
3. Alert if duplicate Hostname found - ie: default FPP name
4. If an FPP instance is detected make it xLight Only and to the best that we can set vendor to FPP (unless it used a cape and we have all the info)
5. When adding a controller, ping hostnames and if they resolve use that to add controller (if user later changes it to IP - there won't be a prompt on next discovery)
