Denormalize Selector

A state selector optimized for avoiding React avoidable re-renders with Redux, Reselect and Normalizr.

An avoidable re-render happens when a React component receives a shallow copy of one of it's properties, however the object didn't "really" change. Meaning A deep comparison of all of the object's primitives would find them identical. This causes a React component to run it's render method needlessly, since the render result would be identical to the last one.
