Make Hilda run and cry when the blacksmith is killed

Hilda also has a new walking position in the town after she has cried next to the burnt remains of the blacksmith building.
Hilda sprite cleanup and emotion updates

Hilda now uses the Emotion code to display her exclamation mark and she has a sad walk after she has finished crying.
Wife cries next to the blacksmith

Blacksmith wife sprite cleanup. If any NPC has a state of "hidden" now it is doesn't get updated or drawn. No need for a blank area on the sprite sheet.
Wife can still be killed when she is crying
