vocx-fc f4611f0a31 Draft: add modules of draftguitools to the proper Doxygen group
This includes `gui_annotationstyleeditor`, `gui_arcs`, `gui_array_simple`,
`gui_arrays`, `gui_base`, `gui_base_original`, `gui_beziers`,
`gui_circles`, `gui_circulararray`, `gui_clone`, `gui_circulararray`,
`gui_clone`, `gui_dimension_ops`, `gui_dimensions`, `gui_downgrade`,
`gui_draft2sketch`, `gui_drawing`, `gui_edit`, `gui_edit_arch_objects`,
`gui_edit_draft_objects`, `gui_edit_part_objects`, `gui_edit_sketcher_objects`,
`gui_ellipses`, `gui_facebinders`, `gui_fillets`, `gui_grid`,
`gui_groups`, `gui_heal`, `gui_join`, `gui_labels`, `gui_line_add_delete`,
`gui_lineops`, `gui_lines`, `gui_lineslope`, `gui_mirror`,
`gui_move`, `gui_offset`, `gui_orthoarray`, `gui_patharray`,
`gui_planeproxy`, `gui_pointarray`, `gui_points`, `gui_polararray`,
`gui_polygons`, `gui_rectangles`, `gui_rotate`, `gui_scale`,
`gui_selectplane`, `gui_shape2dview`, `gui_shapestrings`, `gui_snapper`,
`gui_snaps`, `gui_splines`, `gui_split`, `gui_stretch`, `gui_styles`,
`gui_subeleemnts`, `gui_texts`, `gui_togglemodes`, `gui_tools_utils`,
`gui_trackers`, `gui_trimex`, `gui_upgrade`, `gui_wire2spline`.

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