[React] use Router instead of BrowserRouter

[ittaibaratz]

This is needed in order to allow using the history object to programmatically move between routes.

This is a simple change, and I'll provide a PR when I get to it. It is explained properly here.

Essentially we need to change the following in index.js: `

), document.getElementById('page'));`

to ` const history=createBrowserHistory(); ...

`

This will give access to the history object, allowing it to update routes as a result of state changes.
