Index is in da house

So there are 5 sort properties and 3 filters for the user list, which is translated to
```
5 x 2 * (2 ^ 3 - 1) = 70
```
So if we want them all there are in total 70 indexes only for the user list.. the max on GAE is 200 :)
That one is the default user list link from the user menu
