Pause should not reset the timer. 100pts

[wpeery]

By alternating pause/unpause you can stop a block in its tracks. This shouldnt happen. Estimated 100pts.

There is a timer for when the blocks move down one square in the grid. When pause is pressed the time resets. But the timer should be kept that its before-pause time instead of resettting. F16 OK (100 pts)
