Core: added authenticated and anonymous user to 'view published content'

## Ready State: YES

The default value for 'View Published Content' is only given to administrator +  , and not for authenticated and anonymous users, which it should be (otherwise no one can see published nodes).   This PR updates the role 'access content' so anonymous and authenticated users can view published content.

It also includes updated reference to features 2 (so all the comments are in the diff)

## Deployment Instructions
