Rails 4.1.7 Upgrade: Configuring for Standalone

Initial configuration to make the app work outside of Heroku environment.

Notes:

* Deprecated dynamic matchers have still not been removed. As a result there will be errors.
* Removed references to Bonsai and commented Tire references to retain a reference to index mapping.
* Included elastisearch-rails in the Gemfile
* Upgraded SECRET TOKEN functionality
