In a40b40a the cylinder-hiding functionality was changed,
which made it necessary to keep track of the number of
cylinders. Ironically, that code was removed previously,
as it was redundant. The count was not readded to the
functions called by the planner, making editing of cylinders
in the planner impossible.
I wonder more and more if the models for planner and the
equipment tab should be changed. They are too different.
Fixes #3375
