Subject: Blasting the Base4/5 files.  Updating Controller.php to inherit bits
 from the old Base5.

If a constructor is needed in a controller, call parent::__contruct()

-/**
- * CI_BASE - For PHP 4
- *
- * This file is used only when CodeIgniter is being run under PHP 4.
- *
- * In order to allow CI to work under PHP 4 we had to make the Loader class
- * the parent of the Controller Base class.  It's the only way we can
- * enable functions like $this->load->library('email') to instantiate
- * classes that can then be used within controllers as $this->email->send()
- *
- * PHP 4 also has trouble referencing the CI super object within application
- * constructors since objects do not exist until the class is fully
- * instantiated.  Basically PHP 4 sucks...
- *
- * Since PHP 5 doesn't suffer from this problem so we load one of
- * two files based on the version of PHP being run.
