Bug in core.views.queue_info, is it used anymore?
The code in `core.views.queue_info` contains this:

``` python
            for obj in reserved['build']:
                kwrags = eval(obj['kwargs'])
                reserved_pks.append(str(kwargs['pk']))
```

So it has a typo in `kwrags`. That means the third line of the example won't pick up the correct variable. It might still succeed without a `NameError` as it might be already initialized by another for loop above in the same function.

See https://github.com/rtfd/readthedocs.org/blob/291d7d61e626c1dfb998d9e5d4e5b734a44a7024/readthedocs/core/views.py#L102

I didn't fix it straight away as it seems that the `queue_info` URL is not used anywhere in the project? Do we still have a use for it?

```
$ grep -r queue_info .
./readthedocs/core/views.py:def queue_info(request):
./readthedocs/urls.py:    url(r'^queue_info/$', 'readthedocs.core.views.queue_info', name='queue_info'),
```
