Real URLs

This changes the frontend functionality. Instead of tuning the channel when you click it and then redirecting, it just follows the URL to the channel like it should.

When the channel view is loaded, status is checked immediately and the appropriate things will happen. 

This means URLs are working like they should. You should be able to link to or go directly to a channel and shit should just work.

This is the new flow after the channel view is loaded:

* Status is checked
* If status is `READY`, the player will start playing the stream
* If the request is a `404`, the channel will be tuned and the page will start polling the status of the channel to check if its ready to stream.
