Use the new properties for linked resources to show link direction and type

[giohappy]

Two new properties linked_by and linked_to are returned by the linked_resources API endpoint for a resource, where linked resources are split on "Link to" and "Link from " linkages.
These two properties contain an array of links, with the same structure as the current resources property, with the addition of internal.
The value of the internal property says if the link is managed by the application (true) or explicitly created by the user through the metadata editor (false)

The client will enhance the "Linked Resources" tab by splitting the links into 4 sections:

• Linked to
  • resources inside the resource.linked_to array and having internal=false
• Linked by
  • resources inside the resource.linked_by array and having internal=false
• Uses
  • resources inside the resource.linked_to array and having internal=true
• Used by
  • resources inside the resource.linked_by array and having internal=true

The section will be shown only if the array is not empty.

The client will stop using the deprecated resources property
