ctools_access_get_loggedin_context doesn't fully load current user in context

I found a bug where ctools_access_get_loggedin_context doesn't fully load the current user when building the logged in user context.

This meant fields from the user weren't available.

The logged in user context is currently created like this:

/**
 * Create a context for the logged in user.
 */
function ctools_access_get_loggedin_context() {
  global $user;
  $context = ctools_context_create('entity:user', $user);
  $context->identifier = t('Logged in user');
  $context->keyword    = 'viewer';
  $context->id         = 0;

  return $context;
}

However, the related function ctools_context_create_user never actually loads the user entity ( Because $conf is passed as FALSE and $data ($user object) is not numeric )

See:

/**
 * It's important to remember that $conf is optional here, because contexts
 * are not always created from the UI.
 */
function ctools_context_create_user($empty, $data = NULL, $conf = FALSE) {
  $context = new ctools_context(array('entity:user', 'entity', 'user'));
  $context->plugin = 'user';

  if ($empty) {
    return $context;
  }

  if ($conf) {
    if ($data['type'] == 'current') {
      global $user;
      $data = user_load($user->uid);
      $data->logged_in_user = TRUE;
    }
    else {
      $data = user_load($data['uid']);
    }
  }
  // Load entity if the data provided is a numeric value. This kind of data is
  // passed by some relationships.
  if (is_numeric($data)) {
    $data = user_load($data);
  }

  if (!empty($data)) {
    $context->data     = $data;
    $context->title    = isset($data->name) ? $data->name : t('Anonymous');
    $context->argument = $data->uid;
    return $context;
  }
}

The attached patch simply makes the function ctools_access_get_loggedin_context user the $data['type'] == 'current' parameter, which is supported by ctools_context_create_user and I believe should be used by ctools_access_get_loggedin_context anyway.

The result is a properly fully loaded current logged in user context.

Please review and commit if possible, thanks.
