Easier back jumps in Basic Movement Training (fixes bug #692) The explanation of Back Jumping (2/2) has been simplified and the "hard" part has been made easier by lowering the girders.

But this turned out that this section was too unfair and we have lost at least one player due to rage-quitting, according to feedback.
