If we were able to list default roles and it's permissions we can use this in unit/functional tests to verify permissions and filters. More than that, this gives us possibility to create a mechanism for comparing expected permissions with existing ones. This might be useful after upgrades when users want to check if some important permissions were not added in the new version.

I have a patch that adds this, it's simple. It also adds a simple rake task that does the check. I would like to have this for 1.9 because we would like to merge a big permission review for Discovery 4.0 together with bunch of new tests covering this area which greatly improves the quality.
