- Replace in the projects 'editor' and 'player' the selector
'app-root' with 'editor-aspect' or 'player-aspect' and make a
case distinction unnecessary
- Remove definitions of the property 'local' in `environment`
and `angular.json`

player and editor can be served without commenting in
app module and app component. Use `start-editor-local` and
`start-player-local`
