[Bf-taskforce25] 2.5 io scripts design

[Arystan Dyussenov]

Hi Brecht,

Again I need your help with RNA.

I get a crash when accessing DupliObject.object property.

DupliObject.matrix and DupliObject.ob_matrix can be accessed ok, but not
DupliObject.object.

To reproduce the crash: open animation/dupliverts.blend in
http://download.blender.org/demo/test/test249.zip, select the duplivert
parent and run the following script:

----------------------------------------------------------------------
ob = bpy.data.objects["Plane"]
ob.create_dupli_list()

ob.dupli_list[0].object

ob.free_dupli_list()
----------------------------------------------------------------------

I've checked DupliObject.object property definition, to me it looks ok.
I even defined a custom get function for this property, didn't help.

This crash happens in soc-2009-kazanbas branch, latest revision.
