Fix the process method to have the previous behaviour of reporting an error to Catalyst if a Template::Exception object is returned by the render method (i.e. when render_die is unset or set to 0).
Fix the warning issued about missing the render_die config option to log using the standard Catalyst logging system (rather than Carping directly), and to only issue the warning at debug level / when in debug mode. The severity of this warning will be increased in a later release.
