IP config in Easel so Easel Local could be on a different machine

Should be a minor change, but I’d like to see an option added to the machine config section to change the IP address used to connect to Easel Local. You could default to 127.0.0.0 which is what I believe you use now, but allowing the change will open up some new options. For example Easel Local could be installed on a Raspberry Pi and Easel could be used on another machine to control it. Right now to do this people are installing a serial port emulator which shouldn’t be needed.
