Community Auth Issue

Hi skunkbad,

Thank you for the time. I tried your suggestion but no luck. Still the `sess_regenerate()` function doesn't return the session id. Maybe because if `CI_Session` is loaded first than the `MY_Session` in Community Auth. I can see the `sess_regenerate()` function on `MY_Session` in Community Auth returned the Session ID but the `sess_regenerate()` function on `CI_Session` does not.

Now, if I install the library that has an auto-load of session, the `sess_regenerate()` function will returned null because that function is coming from the loaded `CI_Session`, not from `MY_Session`. The solution I can see now is changing the code in `Authentication.php` from 

Code:

$session_id = $this->CI->session->sess_regenerate( config_item('sess_regenerate_destroy') );

to

Code:

$session_id = $this->CI->session->session_id;

I don't know if this is the better approach but I can see this is the only way to make this plugin compatible with another library that has an auto-loaded session.

Do you think we can consider this as a list of concerned or fixes in the next version?

Thank you very much and I still open for any suggestion of what is the better approach than my solution above.

Regards,
Jay-r
