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.
Aren't we for supporting the default rubocop configuration as much as possible? I realise that this one is hotly debated as in https://github.com/thoughtbot/hound/issues/262 and https://github.com/thoughtbot/guides/pull/171.

From what I've read its largely cosmetic because fail and raise are aliases of the same method right? Seems simpler for newcomers just to stick to rubocop's defaults. Documentation standing as the last disabled cop.
