Twelve Tiny Tweaks

In addition to new types of ground cover, I would really really appreciate the ability to place pavement in blocks of less than 4x4 (1x1 would be awesome, 2x2 would be just fine), or at least be able to start the 4x4 block of pavement on any square instead of only being able to start it every fourth square. This would make designing pathways or entrances to buildings much easier!
