Send a newly created (Inspire) post to the server

[SamUndefined]

Once #30 is completed and users can add a post within the app, we will need to actually send that post to the server for creation. Achieved simply by sending a newly created post from the app through the API the server.

Requires a special API endpoint. "Posts" refers to "Inspire" posts, or the posts displayed along with an action in order to encourage users to take that action.
