title: typescript definition for react-router v2.0 - error `has no exported member 'browserHistory'`
body: <p>I am using <a href="https://github.com/rackt/react-router/tree/v2.0.0-rc3" rel="noreferrer">react-router v.2.0.0.-rc3</a> and typescript. I installed the definition file via <a href="https://github.com/DefinitelyTyped/tsd" rel="noreferrer">tsd</a>. Since they <a href="https://github.com/rackt/react-router/blob/latest/upgrade-guides/v2.0.0.md#using-browser-html5-pushstate-history" rel="noreferrer">changed the <code>browserHistory</code></a> from beeing a mixin to a module, I get the error <code>Module '"react-router"' has no exported member 'browserHistory'</code> on my terminal when compiling the javascript via webpack. Is there an easy way I can modify the <code>react-router.d.ts</code> file to fix the error? Or do I just have to wait until they update the definition file? My app is working fine, it is just the console-error that bugs me.</p>
