Campbell Barton updated his Wavefront OBJ scripts and Ben Omari updated his DirectX 7 and 8 ones (thanks both).  The other listed scripts had minor updates to accomodate the menu changes.
- Scripts in menus:
  renamed Tools to Object, Generators to Add, and Modifiers to Mesh (Metaball, Curve, Surface can be added later), to integrate better in the interface.
- Fixed a bug in Blender.sys.makename: last letter of file extension was being cut out.
