Draft: add modules of draftutils to the proper Doxygen group

This includes `gui_utils`, `init_draft_statusbar`, `init_tools`,
`messages`, `todo`, `translate`, `utils`.

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