If Favorites are not Implemented, hide Stars in Catalog

[tchaddad]

Currently, I think if a GeoMoose app is not configured to use the Favorites option, we still get the "Stars" option appearing in the Catalog items. This can be confusing for users who wonder what the stars are for.

If the stars could be hidden in cases where app.js does not specify app.add(gm3.components.Favorites, 'favorites') that would be a nice enhancement.

Fix for this can be done with CSS:

.layer .favorite {
  display: none;
}

.layer .layer-label {
   display: flex;
   align-items: center;
}

Can we add this to the how-to?
