To decorate a decorator, decorate the inner function.

Spent a couple of hours debugging why every URL on the central server (homepage, etc) was returning the following error:

![central-server-broken](https://f.cloud.github.com/assets/618416/959586/4b40f16a-048e-11e3-8f23-62cdbff57e2e.png)

Turns out it was just a mis-placed meta-decorator.

Has the central server really been completely broken for a month? I haven't run it for a while. But I guess it was probably on a branch that was only recently merged.
