Subject: REST changes: Allow PUT and POST requests to modify members, not just
 entity.

TESTS ARE NOT UPDATED YET.

- Fix item_rest::get() to maintain the proper sort order, which
  requires duplicating some Item_Model code.

- Elide "weight" from the REST version of item

- Adjust the weight of members according to the order they're returned
  from the client.  You can't add or remove members here, you can only
  reorder them.

- Changed the wire protocol to handle more complex values.
  Now "entity" and "members" are JSON encoded.  The Gallery3
  helper does this correctly.

- Changed the wire protocol for tag_item -- now it stores the
  tag and item urls in the entity, not as members.  This is more
  consistent.

- Added missing security for renaming and deleting tags.

- Got rid of vestigial tag_rest::post().  We add/remove tags
  via the relationship.
