2014_8_30 Added Controllers, Models, and Migrations

Controllers added:
-Event Categories Controller
-Post Controller
-Post Categories Controller

Models Added(Migrations added with these models):
-Post Model
-Post Category Model
-Profile Model
You can't HAS_MANY from both PostCategory and Post. You'd have to have one that just belongs to a certain model and another that has many of another model. Change this to `BELONGS_TO` as a post should just belong to a category.
