Display file stats for user.  Feature #9305

The UI looks like this:
![user_stats](https://cloud.githubusercontent.com/assets/298865/5322312/033ecea8-7c8a-11e4-895c-c228cecc6868.png)

I would have expected this test to be rolled into the other two since we are not thinking at stat is valid without a userid now.  Is that a correct assumption?
