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.
