feat(#263): multiple comment fields in one page

[ChathuraGH]

#263 feat
adding code for getting form's parent '#comments' for supporting multiple comment fields in one page.
at >

1. submitDeleteCommentForm
2. submitCommentCreateForm

if we use jquery this is possible with one line.
$form.parents("section#comments").replaceWith(data);
It can be used in old versions that uses jquery. It is working 100%.

without this code when you try to post or delete comment while having more than one comment fields in one page, the posting comments(parent comments) from all the comment fiels get add to frist comment field, When deleting all the deleted fields get updated to first field.

Test the code before merging. I am not 100% sure it works. Even though it work on my pc.

Pull request is incomplete. Because these changes are not enough to support multiple comment fields in one page.

Because, Pagination doesn't work. If one pagination link is clicked, all the comments fields in all the post objects are paginated. Not only clicked pagination comment field.

Expected behaviour >

Only clicked (pagination link) comment field should be loaded with corresponding comments.
