- Add override for URL fetcher by Thomas Jost (d946d6b)

Overriding the default URL fetcher from Weasyprint is often useful.
For instance, this makes it easy to open local files that are exposed on other
subdomains (CDN…) without having to do a single network request, which makes
the PDF rendering *much* faster.

- Add switch for 'attachment' Content-Disposition
