Comments Page Done

Lots of things....

Comments page is ALIVE! It works based on the permalink of the existing post you click on. Using the same methods and gathering posts, it populates the list of comments. I did not do child comments because that would be a lot of work.

Dynamic table sizing
All tables (2 of them) are using dynamic cell heights. Looks a lot cleaner.

Worked on Comment.swift, made it emulate post.swift

Created APICommentController. It's a comment version of APIController.
