Add wind chimes

[AlexMooney]

Summary

SUMMARY: Content "Adds wind chimes"

Purpose of change

Wind chimes can be set up at a base to provide a small music morale buff. When they're added to houses, they can attract zombies.

Testing

Made the new field visible, deployed a wind chime, saw the field go up. Grabbed and moved the wind chime and the field moves. Smashed a deployed chime. Checked the morale effects.

Remaining work

• Pick a useful looks_like for the item and the furniture. I'm open to suggestions!

For a later PR

• Add a crafting recipe
• Spawn furniture in yards, rarely
• Spawn item in lawn and garden stores

Is it possible that the music message could be moved to JSON, as well as the fact that it counts as music, and then the field code changed to fd_wind_sound? That would allow the same field effect to be added to other things that make noise in the wind, so that windmills could creak for example.

@I-am-Erk that's an interesting idea. I'll give it a shot when I get a chance.

i'm not sure how hard it would be but it would be cool if instead of hardcoding fd_wind_chimes you were adding a flag or a bool to fields to use wind to set their intensity. So instead to check for curtype == fd_wind_chimes you'd check for somthing like field.is_wind_dependent. That way other field could be set to use your code.
