Author Created Posts are initially Unapproved

[hannahhall]

As an admin I would like Posts written by non-admin users (a.k.a. "Authors") to be initially unapproved, so that authors are unable to publish any inappropriate Posts without oversight.

NOTE: If an admin writes a Post it should be automatically approved.

You are not going to worry about admin users for this first sprint. Assume all users are authors. Since no admins, posts should be automatically published and not wait for approval. No image uploads for user profile or post
