'administer nodes' should be 'administer comments'

Hi,

In the validate case in comment_nodeapi, there is currently the following:

      if (!user_access('administer nodes')) {
        // Force default for normal users:
        $node->comment = variable_get("comment_$node->type", 2);
      }

The check for 'adminster nodes' should instead be for 'administer comments'. As seen in the 'form admin' case, the comment options are only output if the user has 'administer comments' permission:

      if (user_access('administer comments')) {
        $selected = isset($node->comment) ? $node->comment : variable_get("comment_$node->type", 2);
        $output = form_radios('', 'comment', $selected, array(t('Disabled'), t('Read only'), t('Read/write')));
        return form_group(t('User comments'), $output);
      }

So, the bug I ran into was with users who had 'administer nodes' but not 'administer comments' permission. Everything was posted with comments disabled (the validate case DIDN'T force comments to the default, but neither were they given an option to select anything). This one line patch fixes the issue.

This is present in 4.6 (where I discovered it) and in HEAD.

Cheers,
Eric
