Adding a simplified interface via a static param driven client

Would anyone be interested in something like this?

```php
<?php

require 'vendor/autoload.php';

$response = Guzzle::get('http://www.google.com', array(
    'body'            => 'hi',
    'headers'         => array('X-Foo' => 'Bar'),
    'query'           => array('foo' => 'bar'),
    'allow_redirects' => false,
    'auth'            => array('michael', 'test')
));

echo $response->getRequest();
echo $response->getRawHeaders();
```

This basically adds a [Requests](http://docs.python-requests.org/en/latest/) like interface to Guzzle that might be easier to use for general HTTP stuff.
