added like and unlike views in Django
connected like/unlike to the frontend using ajax calls
added a 'liked posts' page
redirect back to referrer when replying, whether on main or likes page
added template & view for viewing followed posts (mostly stub)
added django views for following & unfollowing posts
merge with S48 because some functionality depended on it
Got rid of following view/page because Ifollowed posts are actually visible on home view
