- `Client::new()` no longer needs a `Handle`, and instead makes use of tokio's implicit default. - Changed `Client::configure()` to `Client::builder()`. - `Builder` is a by-ref builder, since all configuration is now cloneable pieces. BREAKING CHANGE: `Client:new(&handle)` and `Client::configure()` are now `Client::new()` and `Client::builder()`.
