Remove Location module references
Style tweaks
Add doc comment
Use copyProperties instead of mergeProperties
[fixed] sibling array route configs

now you can configure your routes like this:

```js
var extraRoutes = [<Route/>, <Route/>];
var routes = (
  <Routes>
    <Route/>
    {extraRoutes}
    <Route/>
  </Routes>
);
```

closes #193
[changed] Transition#cancelReason => abortReason

Also, transition.abort() now accepts a reason argument that indicates
the reason for the abort. I anticipate that we'll need to add a NotFound
reason soon.
[added] onAbortedTransition, onActiveStateChange, onTransitionError Routes props

Also, removed Routes.handleAsyncError and Routes.handleCancelledTransition
Clean up test harness
[added] <DefaultRoute> component

Also, changed behavior of routes with no name, path, or children so
they act as default routes. <DefaultRoute> is essentially just sugar.
