[FR] Export & import settings

[mbhkoay]

Trying to export the settings and import it again to start over.

To have the sources and profiles exported as a file, that pinchflat will be able to import again, preferably in a format that can be edited, providing an alternative method to modify the settings.

Alternatively can copy & paste the configurations to a text file and redo everything.

Additional context: Messed up somewhere....There is just 1 source that throws an internal server error while trying to access it. The rest is working fine.

Or is there a way to delete a source by deleting a file somewhere?
