This reverts commit 3716524b.

Just change all imports and dependencies.

Instead of handling the visibility checks at render time we keep around a list
of visible routes and emit an event when they change. This way the welcome activity
can mirror what the menu shows and update at the same time.

This field specifies a list of roles that the logged-in user needs to
have to interact with this activity.

In the case of the app-shell this means the activity is hidden until
the user information is loaded after login.

Add a scope so we don't have to care about naming conflicts
and set the verison to 0.1.0 since we don't have a stable API yet.

Group activity names and descriptions so it's mroe clear what belongs together
