Scripts:

- Fixes by Jean-Michel Soler: mod_ai2obj.py, mod_svg2obj.py;
- Fixes by Campbell Barton: obj_import.py;
- Small fix to mod_meshtools.py (fixes bug #1605: http://projects.blender.org/tracker/?func=detail&atid=125&aid=1605&group_id=9);
- Updates by Jean-Baptiste (Jiba) to his blender2cal3d.py;
- Updates to all his import / export scripts (added doc data) by Anthony D'Agostino;
- Update to off_import: support for uv data, by Arne Schmitz.

BPython:
- Removed Object.get and .getSelected (deprecated long ago, we use .Get and .GetSelected) -- fixes #1861: http://projects.blender.org/tracker/?func=detail&atid=125&aid=1861&group_id=9
- Applied patch by Michael Reimpell: quat.c - fix for wrong initialization with newQuaternionObject; Mathutils documentation improvements.
- Stani reported a wrong return msg in IpoCurve.Get (that is unimplemented).

Thanks to all coders mentioned above!
