dotCooCoo d069f0fe98 Variables: selecting a data set sets the objects inside a group that it shows
dataset.select applied a row's values in the order the variables were
defined, and it skips an object inside a hidden group. When a row
showed a group and set an object inside it, and the object's variable
was defined first, the object was skipped while the group was still
hidden: one selection applied the row in part, and selecting the row
again applied the rest. A text variable on type inside the group was
skipped the same way, and a row that hid a group skipped the objects
inside it whose variables were defined after the group's.

dataset.select, dataset.next and dataset.prev now apply the visibility
values that show objects first, outermost object first, then the other
values in definition order, then the visibility values that hide
objects, innermost object first. Of two variables of the same kind on
one object, the one defined last still wins.
