detailed access list

[ArtificialOwl]

remove an issue while adding comment on a file by fixing getAccessList to returns detailed entries:

with $currentAccess:

[
  'users'  => [
    'user1' => ['node_id' => 42, 'node_path' => '/fileA'],
    'user4' => ['node_id' => 32, 'node_path' => '/folder2'],
    'user2' => ['node_id' => 23, 'node_path' => '/folder (1)'],
  ],
  'remote' => [
    'user1@server1' => ['node_id' => 42, 'token' => 'SeCr3t'],
    'user2@server2' => ['node_id' => 23, 'token' => 'FooBaR'],
  ],
  'public' => bool,
  'mail' => [
    'email1@maildomain1' => ['node_id' => 42, 'token' => 'aBcDeFg'],
    'email2@maildomain2' => ['node_id' => 23, 'token' => 'hIjKlMn'],
  ]
]

without $currentAccess:

[
  'users'  => ['user1', 'user2', 'user4'],
  'remote' => bool,
  'public' => bool
  'mail' => ['email1@maildomain1', 'email2@maildomain2']
]

I rebased the commit locally to 27 for testing and it worked as expected.
Writing a comment now leads to an activity as well when you have access to the file by a circle membership.
