Comments are off by default unless command specified

When submitting a node without commands, comments are off, even if comments have been set to "read/write" in the content type settings page. I don't know if this is done on purpose, but i think that if the node type has comments set to "read/write" by default, submitted nodes that do not have commands should have comments enabled. I think the same applies for other defaults (status, promote, sticky).

Here is a simple fix, that should be added to mailhandler_retrieve_message, before the node is submitted :

  $options = variable_get('node_options_'. $node->type, FALSE);
  if (is_array($options)) {
    $node->status = in_array('status', $options) ? 1 : 0;
    $node->promote = in_array('promote', $options) ? 1 : 0;
    $node->sticky = in_array('sticky', $options) ? 1 : 0;
  }
  else {
    $node->status = 1;
  }

  $comment = variable_get('comment_'. $node->type, 0);
  $node->comment = $comment;

I can submit a patch if you want.
