Option not to export Default Take

from John Brown (jcbdigger)

The patch has been modified, some of the changes I rather see applied as separate patches.

This commit adds/changes:
- Option to export XNA compatible armature rotations.
- Option not to export mesh edges.
- Always export armatures as 'Limb' type.
- dont write default cameras or camera switch when cameras are disabled.
- fix for (harmless) error where armature connections were written out twice.

previous order deprecated.

- remove/comment unused variables
- remove unused imports
- fixed some bugs using incorrect variables

also write out deformed meshes as parentless since the bones `own` them.

also option to export lamps was missing.

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

fixes [#25997] Export to X3D reports error TypeError: 'NoneType' object is not scriptable.

most editors (besides notepad) will open these files without trouble.

sort materials so we get predictable output from blender, also add option not to include dates in files.
