Title: Add note to documentation to indicate dashboards.rb may need to be updated during upgrade

Modified README.rdoc to help with `uninitialized constant Admin::DashboardController` issue noted here:
https://github.com/gregbell/active_admin/issues/1587

I should have done this as a feature branch, but was a small change.
