JSON request returns rendered atoms and their meta data

JSON request at atom/fetch/CONTEXT/SIDs has been changed to atom/fetch/SIDs?context=CONTEXT (the context is optional) now returns meta data. The returned data structure has been thus modified:

In Scald 1.0:

array(
'3' => array(
  'full' => 'rendered atom in full context',
),
'5' => array(
  'full' => 'rendered atom in full context',
),
);

In Scald 1.1:

array(
'3' => array(
  'contexts' => array(
    'full' => 'rendered atom in full context',
  ),
  'actions' => array(
    'fetch',
    'view',
  ),
  'meta' => array(
    'title' => 'Atom title',
    'type' => 'type machine name',
    'legend' => '',
  ),
),
'5' => array(
  'contexts' => array(
    'full' => 'rendered atom in full context',
  ),
  'actions' => array(
    'fetch',
    'view',
    'edit',
    'delete',
  ),
  'meta' => array(
    'title' => 'Atom title',
    'type' => 'type machine name',
    'legend' => '',
  ),
),
);

To check whether the user can edit atom SID=5:

Drupal.dnd.fetchAtom('', 5, function() {
  if ($.grep(Drupal.dnd.Atoms[5].actions, function(e){ return e == 'edit'; }).length > 0) {
    alert('Can edit');
  }
  else {
    alert('Can not edit');
  }
});
