New Feature: Inventory

Example:
https://junkepics.com/user/1/inventory/

Users can now own fake items. I've been meaning to do this for a while now, but I forgot about this. For years. It's still pretty unrefined and subject to change, but it has potential for some laughs.

I've taken the liberty of giving you regs some "items", which you can view through a link in your user profile. I'm pretty terrible at gifting stuff, so you get what you get.

I'll update this feature more as needed, ie sell/trade/drop whatever. And if I get this working well, I'll do likewise with people/creatures, so you can pit them against each other, but for now... it's just items.
