Change foliage collision

Now you will understand what I mean. The visible external size and appearance of the foliage will not change in any way, moreover, it will cease to be a solid block, as if it will become the size of a head. This is to make the trees more natural, players will sometimes fall through the foliage, but they will still be able to stand in the "place with a branch", when riding horses, players will rest their heads much less.
