Title: Make lxml clean tree available for user modifications

The cleaned lxml object wasn't available outside readability.

It very useful to ask readability to extract and clean an article and then modify the lxml tree before generating a html text stream.

An example to update image link:
```python
d = readability.Document(html)
d.summary(True)
for i in d.html.findall(".//img"):
# ... some modification ...
summary = d.get_clean_html()
```
