Offer a minute a second as a play speed

Between real time and an hour a second there was nothing to watch a few
minutes of weather or a launch play out at. The speed menu now offers a
minute a second as its second choice.

+  speeds from real time to a week a second, and plays smoothly, holding only
+  when the next weather frame has yet to load, with a spinner by the time
+  while it waits. The time rides in a bubble over the handle. The track zooms
+  with a scroll or a pinch, drags along, and goes to the time under a tap, on
+  a phone as on a desktop. Zooming out on the globe stops while the globe is
+  still in view instead of leaving it a speck (samehkhamis, #1513).
