Flip "Next" section

[AnyaCraig]

Right now, the "next" block preview section shows the next three blocks top down. Because of the way the board is laid out, with blocks coming from the top, it would make more sense for the next block to be on the bottom of the "next" section, with the dividing line above it, and for the block that comes after to be above the line, and the third block to be on top of the section.

This would require less thinking and mental flipping on the part of the user.
