blender/release/scripts/envelope_assignment.py
Willian Padovani Germano 859959b49c BPython:
- fixing bug reported by Paolo Colombo: space handler slinks set for a 3d view were not set when the area got maximized;
- Blender.Object: added object.isSB() method to know if an object is a soft body (has ob->soft != NULL).  Used in fixfromarmature.py.

Scripts:
- updates: batch_name_edit (Campbell), fixfromarmature (JMS);
- additions:
   X3D exporter by Bart;
   Envelope Suite by Jonas Petersen;
   BVH 2 Armature by Jean-Baptiste Perin;
   Camera Changer by Regis Montoya (3R);
   Interactive Console by Campbell (ideasman).
- tiny updates in other scripts.
