Added support for directly uploading to networked 3D Printers running Klipper via the Moonraker API
Adds a new tab in the GCodePlot window called Connection Settings that contains the Moonraker API settings as well as the Serial Connection settings (moved from the General tab).
Currently doesn't support authentication since I don't have auth set up on my own Moonraker instance, but does support the option to automatically start cutting once upload is complete.
Note: I'm remaking this PR using its own branch - which I should have done in the first place rather than foolishly using master.
Original comment from @arpruss:
This is a dilemma. I can't test it, since I don't have any Klipper/Moonraker devices. But I can see it would be useful to some people. If smeone other than the submitter can test it and report, I might be willing to add it.
