• Add config/initializers/callback_terminator.rb

  Newly generated Rails apps have a new initializer called callback_terminator.rb which sets the value of the configuration option config.active_support.halt_callback_chains_on_return_false to false.

  As a result, new Rails apps do not halt callback chains when a callback returns false; only when they are explicitly halted with throw(:abort).

  The terminator is not added when running rake rails:update, so returning false will still work on old apps ported to Rails 5, displaying a deprecation warning to prompt users to update their code to the new syntax.
