Look into improvements for build times

[elvingm]

Build times are way too long and the quick and dirty solution for pulling down Dato data, and linking models is probably the source.

One possible optimization taken from Dato's own code is using their ItemsRepo - see this thread and this example. It looks like this code performs the linking of models for us without us having to handle it recursively as we are doing now here.

Upgrading to the latest version of React-Static might do the trick: react-static/react-static#239 (comment)
