Title: Improved /placeBlock command to use BlockFamily.

- Using BlockFamily to determine the block to place (like in /giveItem commands)
- Improved fetching old block

Question to the architects: Why do I need to determine the old block a placement position? I think it has something to do with the lighting propagation, but shouldn't there be a variant without that check and forcing the recalculation of light.
