Comments should also return a username field to show which user made the comment.

Referring to the work done in branch comment_threads:

Currently, comments look like this upon being returned:

{
  "id": "SOME_MASKED_ID",
  "parent_comments": [
    "SOME_MASKED_ID",
    "SOME_MASKED_ID"
  ],
  "parent_post": "SOME_MASKED_ID",
  "text": "Hello, this is a comment.",
  "replies": 0,
  "children": [],
  "votes": {
    "up": 8,
    "down": 2
  }
},

They should be changed to include an additional field, username, that shows who created the comment. This is because comments are public while posts (confessions) are anonymous.
