A site manager needs to be able to edit and add block content

Problem/Motivation

Seems a user with the manager role cannot edit block content— including the block that says "Use this space for your attribution or copyright information." Not good!

Steps to reproduce

Proposed resolution

Modify the manager role to have added permissions like in this diff from a Drutopia site config export:
