RST structure fix.
Saved mapping metadata handling

  - Allow addition of metadata, such as a short informative description
    of the active/selected scope mapping instanced at the commit stage,
    which will be fixed so that content owners can review the rights
    granted at a glance.
Moved a method up to parent.
Display client's title instead of key to user

  - As the client (consumer) keys are now randomly generated, the title
    will need to be used for human readability.
Scope details on token authorize page.

  - Title attribute added to profiles, which will be used as the
    required succinct description for a given scope.  Description
    attribute can be used for detail.
  - Standalone page for displaying the merged scope profiles to
    resource owners.
