Core pr 5

Coding style and add support for extra parameters to CURL to support proxies.
It's a variable that developers can set in the settings.php file (hidden variable) that allows connections to the data-well. DBC have changed the way we could connect to the data well so using a ssh socks5 proxy is the solution.

```php
$conf['curl_options'] = array(
  CURLOPT_HTTPPROXYTUNNEL => TRUE,
  CURLOPT_PROXY => 'localhost',
  CURLOPT_PROXYPORT => '12345',
  CURLOPT_PROXYTYPE => CURLPROXY_SOCKS5,
);
```
```bash
/usr/bin/ssh -fND 12345 cable.aakb.dk
´´´

The options is used later on in the nanosoap client for which there is a patch in the make file (https://github.com/ding2tal/ting/blob/development/ting.make).
