Thread should have its own message and posts should only be the replies

[vivekratnavel]

Threads must be created with a message and today we create the first post with that message and add it to the thread. Instead the thread should have a message and posts should only contain all the replies. This would make it easier to limit the number of posts sent in the response with a limit parameter such as "limitPosts" to get the latest "n" posts in each thread. This will greatly help with reducing the network load and enhance the UX by lazy loading all the posts only when the user clicks on a link/button.
