Web-based progress/control UI

[jonnor]

At least for serialport, the 'sending' / 'progress' window is running locally on the machine.
This does not work if the machine running the server is headless, like a Embedded Linux machine (RPi/BeagleBone etc).
This is useful so that people can use their own laptops and just connect to the webinterface.

It may be worthwhile to consider something like the JSON serialport server/protocol from ChiliPeppr.
https://github.com/chilipeppr/serial-port-json-server
They have a reference server implementation, and many nice UI tools.

We have also parallel port communication, this part needs a rewrite anyway.
