Possible fix to the 403 page shown to every request on Prod bug.

Enviroment variables in the uwsgi conf file were quoted, meaning that
$AMAZON_AWS.... was being passed to amazon not as the value referenced by
the environment variable, but as the environment variable name itself.

Amazon was returning a 403 as the wrong authentication details were
being passed.

This 403 was then passed back to the app and caused all the requests to
fail.

This did not happen on dev as the variables were set correctly from my bash
script, and so the correct variables were being passed.

I should handle bad responses from all the API's I call, and I should also
write some unit tests to cover this case.

I unquoted the environment variables, I think this should fix
everything....
