add options to import-export configuration files

[hafbtm]

firstly to thank all the people who make this project possible, it's great!
I would like to know if you could add options to import-export sunshine configurations so that it is easier to test configurations of other users and at the same time it is easier to save your presets as commands do - undo and configurations in general

Just copy your config and apps files.
