Show only specified inventory items#834

Basically, to either add an ar where you can show only SPECIFIED items when a user uses the inventory through an autoresponder or a setting that allows you to make it so it doesn’t show up in a user’s inventory when creating an item in the shop. I like to use an item to have a second currency because I always have 2 currencies in my server, but it gets messy because then it also shows up in someone’s inventory.
