* Draft: Draft_Fillet: fix error in #17945
In #17945 the delete option of the command results in an error if subobjects are selected.
* Command should not be available if there is no selection
* Update copyright notice
Fixes#11435
Draft_Fillet could already handle arcs, provided they were not Draft_Arcs. The `_extract_edge` function in make_fillet.py had a strange logic, and could also return a wire which would result in problems later.
Another issue was that the `fillet` function in fillets.py did not handle the order of the edges correctly if one of the edges was an arc and the other a straight edge. The arch had to be selected first to prevent this error.
These messages were perhaps originally intended as a debuggin aid but now add clutter to the output panes. Remaining messges are mostly the result of methods to display attributes of an object (which one could call from the Python console) or actually provide some information which would not be obvious from the circumstances
This includes `make_arc_3points`, `make_array`, `make_bezcurve`,
`make_block`, `make_bspline`, `make_circle`, `make_circulararray`,
`make_clone`, `make_copy`, `make_dimension`, `make_drawingview`,
`make_ellipse`, `make_facebinder`, `make_fillet`, `make_label`,
`make_line`, `make_orthoarray`, `make_patharray`, `make_point`,
`make_pointarray`, `make_polararray`, `make_polygon`,
`make_rectangle`, `make_shape2dview`, `make_shapestring`,
`make_sketch`, `make_text`, `make_wire`, `make_wpproxy`.
These are added to the `draftmake` Doxygen group
so that the functions contained in each module are listed
appropriately in the automatically generated documentation.
The original code was in `DraftFillet.py` which is split
into a different modules like the rest of the workbench.
The object code is in `draftobjects`, the viewprovider
is in `draftviewproviders`, and the function to create it
is in `draftmake`.
