Renamed Item does not reflect in Multiplayer death messages

[ghost]

The name of the renamed weapon when someone is killed by them is not properly reflected in death messages.

Recreating

1. Head onto a server with two users
2. Rename any weapon of your choice
3. Slay your foe with the renamed weapon
4. Read the death message. Does not reflect weapon's name.

This is due to how Terraria generates death messages.
When generating a death message, the item's actual data is not referenced - instead, only the item ID is sent to the death message generator. (The item's prefix ID is passed around in the netcode, but doesn't appear to actually get used.)

I think I may be able to bypass this behavior with the proper methods, however with my current understanding of the code I'm not certain if I can get it to work reliably without extra effort.
