Tested couchapp

...38 tested the couchapp, all seems to behave normally as if the cors proxy wasnt there (this is to be exected, the cors proxy shouldnt be in effect given that the domains match.


What is working:

* couchapp seems to behave normally

What's left to test:

* Chrome App
* Android App
* CouchApp pushing... doesnt appear to work (either due to nginx or due to the cors proxy)

tested with this nginx config:

```nginx

location / {
       proxy_pass http://corsservice;
       proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
       proxy_redirect off;
       proxy_buffering off;
       proxy_pass_header  Set-Cookie;
       proxy_set_header        Host            $host;
       proxy_set_header        X-Real-IP       $remote_addr;
       proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    }

```
