Updating www/p5-Catalyst-Plugin-Session from 0.27 to 0.29

Upstream changes:
0.29 2009-11-04
        - Fix session being deleted when you have a new session after session
          expiry when calling session_is_valid method. Tests for this.
        - Allow ->session to be used as a setter method so that you can say
          ->session( key => $value );

0.28 2009-10-29
        - Fix session fixation test with LWP 5.833 by calling $cookie_jar->set_cookie
          rather than manually stuffing the cookie in the request.
