Subject: [PATCH] Notify the app when a CLI command changes node identity or
 position

set name, set lat, set lon and gps setloc now fire a new no-op
CommonCLICallbacks::onNodeConfigChanged() hook so the application can
react to the change (e.g. re-evaluate automatic region or advert
configuration).
