* feat(cli): Add json import/export of app config
Add the capability to export and import the application config to/from
a json file. The JSON file is LocalState\config.json in the app package
folder. The options are available via the new flags to the settings
command, e.g. `fluent.exe settings --export` and `fluent.exe settings
--import`
Import attempts to merge imported config with existing config, and
refuses to import thigns marked as pre-installed. It attempts to
merge configuration for pre-installed profiles where those fields
are editable, but otherwise discards invalid configuration.
