Removed significant amount of code for reincorporation to a separate GodChat (or rebranded) app. We will eventually get these apps to interact with each other via MissionHub as we aim to sync visitor profile information with MH as the visitor DB. @twinge given this is a significant change in direction I'd love your comments.
This is close to carbon copy of whats written in the controller example given in the **Growing Rails Application in Practice** reference book which by and large gives us the structure for much of the controllers in wtc at the moment.

```ruby
def note_params
  note_params = params[:note]
  note_params ? note_params.permit(:title, :text, :published) : {}
end
```

Should we depart from that exemplar code in order for simplification or should we stick to the book making it easier for people to match the source material to the live project. Your Thoughts?
