[ANDROID] Story view activity comments

[fthdgn]

The story view activity contains a section where comments are listed with the new comment section.

• At the top, there is new comment section.
• Below the other comments are listed.
• Each comments show comment date, last edited date, username (clickable)
• If the comment is one of the comments of user, edit button should be visible.
