Was a naming collision with 'keys' python method, reserve keys/items/values/get for python. Updated animsys_update.py for shapekey data paths. renamed: Particle.hair --> hair_keys Particle.keys --> particle_keys Key.keys --> key_blocks EnumProperty.items --> enum_items KeyMap.items --> keymap_items noted: http://wiki.blender.org/index.php/Dev:2.5/Py/API/Updates#Since_2.56a
ui/ --> startup/bl_ui op/ --> startup/bl_operators scripts/startup/ is now the only auto-loading script dir which gives some speedup for blender loading too. ~/.blender/2.56/scripts/startup works for auto-loading scripts too.
