Temporarily Disable strong_params

I was recently doing a Rails upgrade. This old version of the app wasn't prepared to deal with strong_params right away. I already had a pile of migration path TODOs and fixes on top of addressing the strong_params issue. I decided to put off dealing with strong_params by adding this line the main controller.

# app/controllers/application_controller.rb
def params
  request.parameters
end

This bypasses the strong_params check for all controllers inheriting from ApplicationController.

Remember, this is a temporary fix. You'll eventually want to adhere to strong_params for your mass assignments.
