[28ac419] Item durability bars and NPC interaction

There seems to be a buggy interaction when NPCs shout a threat at you (Put down the !) and the new item durability bars, a skippable DEBUG error occurs and the following lines are logged in debug.log:

10:50:13.763 : src/npctalk.cpp:3275 Bad tag. ‘<color_green>’ (13 - 25)
10:50:15.443 : src/npctalk.cpp:3275 Bad tag. ‘’ (20 - 27)

Ty for reporting. Fix pending: #11268
