title: Change URL without transition
body: <p>I have a question concerning the Ember routing system.</p>
  
  <p>In my Ember-App, I have a simple leaflet fullscreen map. The center and zoom level of this map are coming from the URL query parameters. Now it would be nice to have a simple way to keep this query parameters in sync with the map position. So when somebody moves the map, I would like to change the url query parameters to the new values. </p>
  
  <p>When I use a simple <code>transitionTo</code>, I start a loop of changing the map and updating the query parameters changing the map again and so forth.</p>
  
  <p>So my first idea was to get the location implementation from the router and changing the url manually. But I do not know how to do that. And it also feals wrong using Ember this way.</p>
