User tests: Successful: Unsuccessful:
This PR fixes all reportable PHPCS issues in the admin app outside the components folder and application.php and framework.php files in the includes folder (as reported at http://mbabker.github.io/jcms-codestyle/). In doing this, I've also changed the exceptions on the administrator folder so that only the files previously specified as not touched (and templates, which are permanently exempted from most rules) are still exempt from specified rules.
