Title: Width and height params to Connections.Picture#picture

See: https://developers.facebook.com/docs/reference/api/user/

```
HTTP 302 redirect to URL of the user's profile picture (use ?type=square | small | normal | large to request a different photo). If you specify ?redirect=false, this connection will return the URL of the profile picture without a 302 redirect. Additionally, you can specify width and height URL parameters to request a picture of a specific size. This will return an available profile picture closest to the requested size and requested aspect ratio. If only width or height is specified, we will return a picture whose width or height is closest to the requested size, respectively; if width=height, we will always return a square picture. If the "October 2012 Breaking Changes" migration setting is enabled for your app, this connection will return a JSON object with url, width, height, and is_silhouette fields, where the width and height specify the actual dimensions of the returned picture; is_silhouette is a boolean which specifies whether the profile picture is the default picture (i.e. the user has not uploaded a profile picture).
```

This PR adds support to `width` and `height` parameters. Now user can request picture with different sizes by specifying either `type` or `width` and `height`, which come in handy when you stream userpics directly from facebook to enduser.
