title: 400 error returned when using Box2.0 Delete method
body: <p>I am using Box 2.0 API to delete a file.  Using Postman, i enter the following:</p>
  
  <p><a href="https://api.box.com/2.0/files/2605672883" rel="nofollow">https://api.box.com/2.0/files/2605672883</a></p>
  
  <p>specifying the DELETE action.  I've set the authorization header appropriately.  When I submit the request, I get the following error:</p>
  
  <p>{
      "type": "error",
      "status": 400,
      "code": "bad_request",
      "help_url": "http://developers.box.com/docs/#errors",
      "message": "Could not parse JSON",
      "request_id": "4934716064fff2a0a70988"
  }</p>
  
  <p>This makes me think that i need a JSON object as part of the message body, the documentation specifies that the File ID is the only thing necessary as part of the request.  Is this a bug or am I doing something wrong ?</p>
  
  <p>thanks</p>
