Remove ActionView inline logging to ActiveSupport::Notifications and create ActionController::Base#log_event, so everything can be logged within one listener. Also expose log_process_action as a hook for different modules to include their own information during the action processing. This allow ActiveRecord to hook and any other ORM. Finally, this commit changes 'Processing' and 'Rendering' in logs to 'Processed' and 'Rendered' because at the point it's logged, everying already happened.
