Version 2.3.0

Release Notes:

Changes for Winter '18 release.

Changed attributes with object types to Maps (see this tweet: https://twitter.com/GrayJustise/status/912739993008738304).

Winter '18 gives the ability for component methods to return a value! Subsequently, getState has become an official part of the component api, instead of an expando. Yay!

Also cleaned up doc references, and now there is an actual auradoc component or Redux.
