Draft - Allow to export Drawing pages to DXF - fixes #1686
* Uses DXF algos of the Drawing module instead of the Draft dxf library * Uses a DXF template with the same name as the SVG template, if existing * Only Draft, Arch, Part and Annotation views are currently supported * Drawing module's projectToDXF() now returns only a fragment instead of a full DXF file
