add hydrateRender to Resolver

[DarylThayil]

Lets us take advantage of the ReactDOM.hydrate method.

• add tests for render / hydrate render method
• add jsdom so we can test browser

@pwmckenna can I get a review :)

[DarylThayil]

closes #137

[DarylThayil]

I spoke to @pwmckenna

feedback was
[ ] 1 pr for tests a separate pr for hydrate
[ ] rename hydrate render to just be hydrate
[ ] dont bump peer deps to require react 16, instead have hydrate function check for hydrate funciton in reactdom and if it s not available, either throw error or fallback to render (id probably throw?)
