[Catalyst] Make Catalyst NOT reset a cookie on a per action basis

[Steve Kleiman]

Thanks for taking a look. I thought I had it isolated but seems not.  
Tried what you suggested below but the instigator of the cookie  
happens at a different juncture.

The instigator for a 'Catalyst::Plugin::Session' cookie being set is  
'Session::prepare_action'. The method calls 'sessionid' which  
ultimately invokes the resetting of the cookie.

So a more refined question would be, is there a way to wrap only  
'Session::prepare_action' whilst not wrapping all the other  
'prepare_action' methods? I've tried the following but have had no luck:
> before 'prepare_action' => sub { ... }
> before 'Session::prepare_action' => sub { ... }
> before 'Catalyst::Plugin::Session::prepare_action' => sub { ... }

Thanks for the help....
