Updated Role Permissions

We have made two small updates to our permissions today: Managers are now able to approve builds, and everyone can restart builds.

Since launching the manual approval we've received feedback on what could improve that feature, and the one that stands out is that restricting approval to only owners is not flexible enough, so we've expanded the permission to users with Manager roles as well.

We've also heard that quite a few of you are using the contributor role for regular team members, and not allowing them to restart builds creates an overhead of them requesting build restarts etc. From today, all types of users are able to restart builds.
