Title: Need a way to customize fail behavior in menus/param menus

Currently, if a param menu fails because it can't find the parameter referenced, you get a 404. There's no easy way to customize that behavior for situations where you want something else to happen.

We should implement a LocParam or something that you can tack on to a menu definition that allows you to specify custom fail behavior.
