Luigi in Mega Man world (#127)
* uniblock-demo: reset background to black * warning about quantization * some luigi love * update cell documentation * add unit test for move of stdplane * MoveToLowerRight unit test * ncplane_move_yx(): error to move stdscr * better box permutations test * luigi in megaman2 world * stats: don't print 'em if we haven't got 'empull/138/head
