This fixes Zombified Ian

When Ian(or other Corgi's) are dead, and you put something on their head, instead of the normal message which appears as when they were alive, this is now shown : 

usr << "<span class ='notice'>There is merely a dull, lifeless look in [real_name]'s eyes as you put the [item_to_add] on \him.</span>"

Thus no more zombie Ian when dressing his corpse up!

Fixes #3650
Nope, I tested it. If its no-drop, you still cant put it on Ians head
