Spotify apps api tips

Firstly, I was having problems accessing port 3000 on localhost, so I switched to pow,
so I could access http://spotview.dev (http://pow.cx/)

Secondly, the manifest.json file is only reloaded when you close and reopen the app,
so when you add your http://myapp.dev to the RequiredPermissions array, make sure you
close and reopen.

Finally, you need to set a response header of Access-Control-Allow-Origin: *.  I did this
in rails with a filter in the controller, but you could do this more cleanly with rack 
or a custom responder.  My (slightly dirty) solution:


class ApplicationController < ActionController::Base
  ...
  before_filter :set_headers
  def set_headers
    response.headers["Access-Control-Allow-Origin"] = "*"
  end                                                                                                                                                                                                                                                                                                                                                                                                                   end
