v3.11.0: useAsync

It's finally here: the useAsync hook. This adds a very promising new way to use React Async, without the need for wrapper components. An important milestone.

useAsync is a React hook that makes working with Promises a breeze. It provides metadata such as isLoading and startedAt and deals with race conditions and promise cancellation.

A working usage example is provided here: https://github.com/ghengeveld/react-async/tree/master/examples/basic-hook
