Cow Barn Big v1.0.0.1

These are the two large cow stalls from the game with built-in ball triggers. And the collision check has been expanded.

Changelog:
- Terrain and vegetation in the area of the pasture no longer change when placed
- New store images

Ball triggers for straw and the feeding robot were installed.
Furthermore, the stables can be placed a little easier.
But be careful, this works in a similar way to Placeanywhere.
