Reshape the rest code to be more consistent with regards to

relationships.  Now when you view a resource, it has 4 top level
elements:

url: the url of this resource
resource: array of key value pairs describing the resource
members: array of urls to members of this collection
relationships: array of array of members.

Relationships are a special type of collection that links two
different resources together.  To remove a relationship, just
DELETE its url.  To create a relationship, POST to its
collection.

Individual modules can add their own relationships to any
resource via a callback mechanism.

Example:
  Array(
    [url] => http://g3.com/rest/item/1
    [resource] => Array (
      [id] => 1
      [album_cover_item_id] => 4
      [captured] =>
      [created] => 1264056417
      [description] =>
      [height] =>
      ...
    )
    [members] => Array(
      [0] => http://g3.com/rest/item/2
      [1] => http://g3.com/rest/item/3
      [2] => http://g3.com/rest/item/4
      [3] => http://g3.com/rest/item/5
      ...
    )
    [relationships] => Array(
      [tags] => Array (
      [0] => http://g3.com/rest/tag_item/2,1
      [1] => http://g3.com/rest/tag_item/23,1
      )
    )
  )
