almost missed it - statistics update

[Lutz Vieweg]

To add one more statistic: For the first time (and only since a few days),
the "version 4" subsurface video tutorial on archive.org now has more
"views" (4,572) than the first version that I made for subsurface v3 (4,479).

IMHO that indicates there are still completely new users - which did not try
subsurface when it was at version 3.
