Automatic orientation

[eried]

Have you though on adding something like https://github.com/nallath/CuraOrientationPlugin ?

It works really well in Cura (I use it all the time). I know it is a dumb nuance but with that the user could omit that parameter from the plater.conf file

If you do a PR I would be ok reviewing it Maybe we can have an option that invokes an external tool to handle part orientation on the plate
