Major improvements

• <Link> now respects modifier keys!
• <Link> now accepts either a string or an object like so:

{
  pathname: '/yo/this/is/a/url',
  query: {
    some: 'stuff'
  }
}

• <Link> comes in two flavors now: <Link> (old behavior) and <PersistentQueryLink> (persists the previous query string unless the href prop provides one). Since you'll probably just use one or the other, this is a nice pattern:

import { PersistentQueryLink as Link } from 'redux-little-router';

• Query string support is fixed across the board!
• Added a util that sets up initial state on a server-side render. This correctly sets up query strings on the initial location dispatch.
• The history listener now lives in the store enhancer. The middleware no longer lives in the enhancer and must be used separately due to middleware order issues.
• The store enhancer's reducer enhancer (enhance!!!) now supports redux-loop.
• The current route info now lives at the top of the router state tree like it always should've (no more router.current). You can still access the previous route on router.previous.
• New Fragment component that shows or hides children based on active routes (and even conditions of those active routes).
• New provideRouter adds the router context to a top-level component. This means that <Link> no longer requires you to pass in dispatch and history (THANK GOD).
