0.9.0

After 11 months of development, I'm happy to announce the availability of version 0.9 of Askama, the type-safe, compiled Jinja-like template engine for Rust. This has been a long release cycle; mostly I've spent quite a bit of time trying to figure out problems with how to manage Askama's built-in integrations. In the end, 0.9.0 shipped with the integrations problems unsolved, but they were solved shortly thereafter.

• Upgrade Actix-Web integration to Actix-Web 2.0 (#286, thanks to @DCjanus)
