[Catalyst] storing a list of items into the session

[Pierre Moret]

Thanks for your suggestion, Stephen! I tested it and - after some slight 
tweaking - could make it work the way I want. :-)

But I'd still like to know why my original version doesn't work. Passing 
"$c->model('MotsDB::Mandator')" to a template via the stash works 
perfectly in an action without 'redirect'. But since my login action 
ends with a redirect, I tried passing "$c->model('MotsDB::Mandator')" 
via the session or via the flash. Both didn't work. Me confused...
