Draft: add modules of draftfunctions to the proper Doxygen group

This includes `array`, `cut`, `downgrade`, `draftiffy`, `extrude`,
`fuse`, `heal`, `join`, `mirror`, `move`, `offset`, `rotate`,
`scale`, `split` and `upgrade`.

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