Planner: make cylinder-model subobject of planner-model

The cylinder-model had an instance() function, but actually
there were two cylinder models: one used by the equipment tab,
one used by the planner.

This is misleading. Therefore, remove the instance() function
and make the cylinder-model a subobject of the planner-model.
