Added scaleStack property to decorators

- Added scaleStack to decorators. It allows the size of the stack to scale to the size of the cave, using stackMin and stackMax as a min/max percentage
- Fixed stacks missing a block in size when the top block isn't defined
- Changed decorator stacks of a single block to place the top block instead of the body
- Fixed tab sound playing to other players
