Remove json parsing

This solves a couple problems:

1. Poison was pretty out of date (so trying to use the lib caused
version conflicts with the version we were already using in our app)

2. Our draftjs content wasn't stored as a string, it was stored as a
map.  Removing json parsing will let the user parse it if they need
to (in whatever way they want), and let those who don't need to use
it out of the box.
