Updated to use $servertarget (introduced in mIRC 7.34) for identifying the twitch connection. The old methods for identifying the twitch connection have been removed.

I also updated the script so that passwords for multiple nicknames can be saved. You can switch between nicknames using /twitch_nick (you will also need to reconnect). Only one can be connected at a time (this is by design).

For a while a few of the IP addresses hosting twitch chat didn't have port 6667 available, so the port can also be changed more easily in the script now. Twitch chat listens on ports 80, 443, and 6667.
