Use the auto-discovered web interface port before falling back to Telnet

[dotgrid]

My Denon receiver seems to be operating on an unusual port number (which appears to change). The auto-discovery works perfectly, and identifies the correct port number in foundReceivers[index][1].

However, the discoverControlInterface function tests three possible ports before moving to Telnet. My setup would work if this function checked four ports before falling back to Telnet...

1. Port 80
2. Port 8080
3. Custom port number if specified in config
4. Port number obtained in foundReceivers[index][1]
