Fixes issue79 by removing the name from the "no ratings" dialogue. To retain the context, adds the link to the ratings page, which behaves just fine even with no ratings logged for a user.

The alignment issue was solved by changing the text to h3. To keep the length short enough to fit, I had to remove the username from the text to stop ugly wrapping.
