Clean up PHPCS Suggestions

This PR takes care of all `phpcs` suggested fixes, excluding `Tests` and `phputf8`.

I did, however, learn something about the Twitter package. In `Joomla\Twitter\Search` we have a method called `search`, which happens to correspond to a PHP 4 constructor for that class, and even works as the constructor in PHP 5.4 (haven't tested other versions)

This presents a problem, because the parent constructor from `Joomla\Twitter\Object` doesn't get called, I don't think, thus causing the class to not work.

I'm not sure what to do about it.
