BotShopRegister and FVShoppingRegister(FruitVeggieStand) integrations

It looks like Twallan had a plan to integrate the FruitVeggieStand consignment, unfortunately that particular consignment is different from the others, as it's not global but it's instantiated for every FVShoppingRegister. That means adding it will require some thought. For now, this will do.

Commit #3 : ErrorTrap needed dereferencing for BotShopRegister consigned objects.

Commit #4 : Also dereferencing for FVShoppingRegister consigned objects. This should also resolve some of the Unhandled references reported on the wiki (such as ingredients).

Commit #5: Last, added FruitVeggieStand to the Consignments Cleanup and I think that's it.

Commit #6: By saying 'Last' in #5 I angered Murphy, so this one is to fix a little mistake made in the previous commit.

Note : ErrorTrap, Overwatch and Consigner need Sims3.StoreObjects.dll referenced in the project, I didn't push that change cos my projects are for VS2012, so you will need to add it to the source.
