Arvados

• workbench 1 "Arvados test login" form looks super ugly, completely unstyled. Should we make wb2 the default, at least in the demo?

• workbench 1 login form gives no indication of what to do for a brand new arvbox. Only when clicking the "Log in" button (without providing username/password) does the help text appear that says

  The "test login" users are defined in Clusters.[ClusterID].Login.Test.Users section of config.yml
If you are using arvbox, use "arvbox adduser" to add users." 

• workbench 1/2 login forms say "username" but they really want the email field as per

  $ ./arvbox adduser
/usr/local/lib/arvbox/edit_users.py <path/to/config.yaml> <clusterid> add <username> <email> [pass]
                                    <path/to/config.yaml> <clusterid> remove <username>
                                    <path/to/config.yaml> <clusterid> list

• workbench 2 is using a token that is not attached to a privileged user, so the "Current token" in the dropdown gives the error "Forbidden: this API client cannot manipulate other clients' access tokens. (req-750algt6pabl12xbbqgg)"
