Multiple printers access from 1 orca slicer instance.

[dweenz]

My idea is to have access to all my printers from one instance of Orca. When you add a plate you would be able to designate each plate their own printer. Then depending which plate you slice and send print from could open the web gui in device tab. Which if multiple are open could have tabs to select between each printers web gui. I know most people are fine with opening multiple instances but I feel this could be a move forward for productivity and ease of multipart and color prints transferring between printers work loads.
