now, multiple 2D bezier objects can be exported!

Hey Martin

Added some smaller changes to the script. Now one can easily select multiple 2d curves, and export them in one go!

The size of the Inkscape document/SVG is equal to the largest bounding box of the curve objects. - And all resulting curves in the SVG are just exported on top of each other. But since the user needs to move the curves around anyway and place them how he wants them for laser cutting (for example), this shouldn't be a problem.

Your idea for the adjustments of the gaps for the connecting parts (around 0.125 mm - should be adjustable in the exporter) is quite tricky. May we could try to scale all line segments a little outwards in direction of the "normal" of the curve... I didn't try that yet though, it's quite tricky. - It would also be nice to be able to work with normal meshes and the "Mark Seam" feature of Blender to mark the cuts. It would be great if such a mesh could be automatically UV unwrapped somehow and converted to an accurate SVG. You could use all the mesh modeling tools of Blender (link snapping etc.) and construct everything as a mesh which is easier than with curves IMHO... But that's for later :)

Best wishes,
