New BUGITEM command to attach a specific item to a reported issue

[Rias]

Per the changelog: "The BUGITEM command can now be used to make a bug report specifically about the item currently being held in the character's right hand. The syntax is otherwise the same as the BUG command. Simply hold the buggy item in your right hand, then type BUGITEM <bug info here>. (For those who can't resist including a space, BUG ITEM <bug info here> will also work.)"

This is going to make finding and fixing the specified buggy items so much easier for us, so please everyone do your best to keep in mind that this command exists, and to use it for your buggy items! If a buggy item is a stationary type that can't be picked up, a regular old bug report can be sent from the room the item is in, since those tell us the location the bug report was sent from, and we can just zap over there and find it in the room.
