fedora-rs 0.2.2

I'd like to announce the latest release(s) of the fedora crate, which bring a lot of improvements:

• provide a simple Session interface
• implement an AnonymousSession without authentication
• implement a working OpenIDSession with authentication via the Fedora OpenID endpoint, for example, for interacting with bodhi
• nicer API that takes references instead of taking ownership of values, where possible
• document all publicly visible items (modules, functions, structs, traits) - browse the docs on docs.rs

Detailed release notes for all releases are provided in the NEWS.md file in the GitHub repository.
