Sprint 2/Anonymous Posting/Implement Core Functionality

[VallinZ]

Description: The assignees need to fully implement the anonymous posting and reply functionality and local testing is required to make sure no bug is introduced.
Estimated effort: 12 hours
Dependencies: Anonymous Posting UI Updates and Account Setup
Milestones: Finish in Sprint 2
Acceptance criteria:

• When the the anonymous posting mode is on for the users and users decide to be on the anonymous posting status, anything the user post should not reveal the users identify, such as username, with one exception: admins. Any post made under anonymous should be visible to the admins of who the owner of the reply is, but for anyone else, there should be no display of username and the icon of the user.
