Draft: add modules of drafttaskpanels to the proper Doxygen group

This includes `task_circulararray`, `task_orthoarray`,
`task_polararray`, `task_scale`, `task_selectplane`,
`task_shapestring`.

These are added to the `drafttaskpanels` Doxygen group
so that the functions and classes contained in each module
are listed appropriately in the automatically generated
documentation.
