Drupal 8 port

Attached is a patch for Drupal 9/10 compatibility. To install @bmunson's Drupal 8 port and apply this patch, do the following:

Edit composer.json and add...

    "repositories": [
        {
            "type": "package",
            "package": {
                "name": "bmunslow/drupal8-badbehavior",
                "version": "dev-master",
                "type": "drupal-module",
                "extra": {
                    "installer-name": "badbehavior"
                },
                "source": {
                    "url": "https://github.com/bmunslow/drupal8-badbehavior.git",
                    "reference": "master",
                    "type": "git"
                }
            }
        }
   ],
...
    "extra": {
        "patches": {
            "bmunslow/drupal8-badbehavior": [
                "patches/badbehavior-d10.patch"
            ]
        }
    },

Do not replace the entire repositories and extra sections but add if there are already existing repositories and/or patches.
Then run:

composer install

Ideally, these changes should eventually go into a 9.x branch in this project but this is a workaround until the maintainers have the time and willingness to update.

I noticed there was an error when attempting to access the logs. The attached patch fixes `Symfony\Component\HttpKernel\Exception\ControllerDoesNotReturnResponseException: The controller must return a "Symfony\Component\HttpFoundation\Response" object but it returned a string ("Bad Behavior is not installed correctly. See the README.txt for installation details.")`. Please disregard the earlier patch.
