[Hakaabi]

Acceptance criteria:

-back-end:
when the checkbox is clicked isAnonymous turns to 'true' overriding post user information to 'Anonymous'
when the checkbox is clicked isAnonymous turns to true which displays topic's user object to 'Anonymous'
when the checkbox is not clicked, it should not edit the topic and posts data to anonymous

-front-end:
once posted, the displayname shows 'Anonymous'
when looking the general discussion page, anonymous posts show no avatars
Posts posted anonymously show no user data
When hovering over posts posted anonymously it should show 'anonymous'
when a post is not posted anonymously, it should display the user's information and display their information.

This issue was resolved by editing the controller 'composer.js' and index.js in topics data structure.
