Draft: add modules of draftobjects to the proper Doxygen group

This includes `array`, `base`, `bezcurve`, `block`, `bspline`,
`circle`, `clone`, `dimension`, `draft_annotation`, `draftlink`,
`drawingview`, `ellipse`, `facebinder`, `fillet`, `label`,
`patharray`, `point`, `pointarray`, `polygon`, `rectangle`,
`shape2dview`, `shapestring`, `text`, `wire`, `wwproxy`.

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