Subject: [PATCH 1/3] Websockets support

Added `Upgrade` and `Connection` headers to the template to allow nginx to [upgrade a request](http://nginx.com/blog/websocket-nginx/).

```
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
```

These headers are only added if a `WEBSOCKETS` environment variable is defined.

 ### Multiple Ports
 
 If your container exposes multiple ports, nginx-proxy will default to the service running on port 80.  If you need to specify a different port, you can set a VIRTUAL_PORT env var to select a different one.  If your container only exposes one port and it has a VIRTUAL_HOST env var set, that port will be selected.
