Match <Route> props API with react-router

[dennisgl]

Reference: https://github.com/ReactTraining/react-router/blob/v4.3.0-rc.3/packages/react-router/modules/Route.js#L118-L127

Issues: Previously, to support <Router onRoute={() => {}}>, we made use of <ReactRouterRoute render and rejected <Route render. In addition, we dropped support for <Route children as a render prop.

Main changes: support props.render and props.children(as a function/render prop)
