Title: adding naive/trivial support for cdata

This makes it simple to invoke XML\Writer::write() on an array with cdata
things like so:

```php
$writer = new Sabre\XML\Writer();
$writer->openMemory();
$writer->setIndent(true);
$writer->startDocument('1.0', 'UTF-8');
$writer->write(
array(
'my-sweet-node' => array(
'a-cdata-node' => new Cdata('some cool text in a cdata')
)
)
);
```

```XML

some cool text in a cdata

```
