Update reviewer's list and requestor list.

Problem description
===================

The review page could be extended.


Changes description
===================

* Update reviewer's check list
* Update the information for review requests.  Move the information that is not related to review message, out of that section.

Whiled doing review I always forget to check the reviewer's list.

I was thinking that maybe I can extend the GitHub Chrome extension to allow including or showing the reviewr's checklist somehow in the GitHub Pull Request
