Changed the way materials are exported to better work with DirectX's Phong-esque default specular shading.

disable polygroup by default too.

add mesh extras, gemstones, twisted torus, gears & 3d function surfaces
Now in folder add_mesh_extra_objects under 1 init file.

- Bug fix: hasSmokeSimulation lacked parenthesis

also option to export lamps was missing.

Added missed copyright entry in add-on info block -- svg-arc to
blender beziers calculation was made by JM Soler.

JM, sorry for this :)

Thanks to Yousan Noriyuki.

*Commented out non-manifold check on returned shards, it prevented open meshes to be fractured (e.g. Suzanne).
*Enhanced UI of Fracture Group op.

Added option for smoothing export - Face/Edge/Off.

Fixed the select smoothing face that was not working. Added console output for making sure it working or not on the button.

- Export: Selected Objects no longer exports children of the selected objects as well.

Updated the grease pencil layer conversion to work in Object mode instead of Edit mode, for GPENCIL_OT_SURFSK_add_surface and GPENCIL_OT_SURFSK_strokes_to_curves.

Indentation fix: if assigning a material already on the object to a selection of faces in edit mode the script would do nothing

  * On OSX, copy the Python lib folder to sit alongside the .app instead of the Unix executable.
