Version 0.9.0

Some time has passed since the last release.
This new release will bring less bugs, more commands, experimental async support and better performance.

Highlights:

* Implement flexible PubSub API (redis-rs#136)
* Avoid allocating some redundant Vec's during encoding (redis-rs#140)
* Add an async interface using futures-rs (redis-rs#141)
* Allow the async connection to have multiple in flight requests (redis-rs#143)

The async support is currently experimental.
