More "recent Growl alerts" than 5 in the menu

[Fofer]

I would like to see a configurable setting, say, a pull down in the prefs, that lets me see more than the mere 5 items that appear in Growl 1.3's menu.  Ideally I'd probably set mine to 20.  Being able to only see 5 isn't helpful, and that's *after* pruning which apps are logging.
