lgtv tv on sends request to the TVs IP address and not 255.255.255.255

[cbirchinger]

More recent versions started to send the magic wakeonlan packet to the TV's IP address instead of the broadcast IP

tcpdump comparison:

FAIL: $ ~/.virtualenv/lgtv/bin/lgtv --name tv on 17:27:33.826836 IP 192.168.1.7.49369 > 192.168.1.21.9: UDP, length 102

WORKING: ~/.virtualenv/lgtv/bin/wakeonlan b4:b2:91:xx:xx:xx 17:28:29.942674 IP 192.168.1.7.54168 > 255.255.255.255.9: UDP, length 102 (So the wakeonlan pulled as dependency is capable of doing the right thing)

Wake on LAN only works when the packet is sent to the broadcast address because the IP of the TV is not active while the TV is in standby.

This fixes it for me. Removing the ip_address argument makes wakeonlan default to 255.255.255.255
