Removed CI_Loader::initialize() and moved its logic to the constructor.

That method used to be called by the CI_Controller constructor
and was required because of the possibility to instantiate the
Controller class twice due to 404_override, and so some properties
needed to be reset.

Following the last commit - this is no longer the case.
