Edited classes to mirror uzyn's original library

uzyn's library is now on version 0.4.3. I've upgraded your code to resolve some critical changes. Several bugs were fixed in the last 9 months while this codebase was unmaintained. For example, methods like mapProfile(), clientGet(), serverPost() were modified. Also session settings were updated.

Could you care to pull in the changes so that Codeigniter users can use the latest version.
