The package karma-spec-reporter is to show more info about run tests on 
the console.

Numbers on the test files refers to the version (2 digits for minor; 
patch number ignored).

The default value of 1 MB was too low for the player, which currently
requires 1.18 MB.

The theme file is now project specific because Angular demands assets
to be part of the project.
It also differs in content: The editor theme is only applied to canvas
elements. For the player every checkbox and radio button is affected.

The components now again use the default color of 'accent'. The custom
theme now has the green as accent color and no longer primary.

Used in checkboxes and radio buttons, which are now green.
The secondary is unused but for safety set to the same as the default
theme should be.

The editor package is larger than that. So the build fails without the 
higher limit.

- 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`
