This required some interface changes (mostly changing Laravel's or Symfony's request and response classes to those of Zend's Diactoros. Some smaller changes to the execution flow in a few of the abstract action base classes, but nothing substantial. Note: The request and response classes are immutable, so we usually need to return new instances after modifying the old ones.
