adding expansion field in item DB?

[Krran]

I can't think of a quick way to go about it off the top of my head. I think such a feature would be useful to people though, including myself.
If you want to get strict about it you would have to disable quests too that give out-of-era items, as well as NPC pops like fabled things.
If I think of a snazzy idea of how to script it or something I will post it, but don't hold your breath, heh.
