Oh god damn. The last thing we need is software to create bricks.
The current system (people who are smart enough to make bricks make bricks) works just fine. If we have some easy-stuff someone for any dumbass to go and make a brick, we'll be flooded with cruddy bricks that don't even snap to grids. Furthermore bricks don't even download from server to client so nobody would be able to see them without having to go download them before joining.
