[Feature Request]: A button to export and option to import server settings

[bjazmoore]

Feature Description

A button on the bottom of a successfully tested server setting that would allow the settings to be exported to an encrypted file.

Another button on the server type selection would allow importing of the encrypted server settings file.

The use case is discontinuing the use of a specific Publii website in favor of a new one that will be hosted on the same host. This would save the step of recreating a token for those servers that require one - if the token gets lost.
