Move the toolkit-neutral parts of File > Export/Export All, Plate > View
in CAD and the nest report commands into OpenNest.Desktop: export formats
and suggested per-plate file names (now free of characters any platform
refuses), the placement list, DXF/SVG writing with the view image left to
the front end, opening a file in its associated program on Windows, macOS
and Linux, the report file name check, capture with catalog density, the
machine's thickness name and saved cut-time settings, and viewed-report
temp folders. WinForms calls the shared code; its behaviour is unchanged.
