* Applied a small fix to a bug reported by Guignot:

When a script that used setAttr for Camera Data objs (the bug also
    affected some other modules) was executed multiple times, Blender
    would crash after, let's say, the first 5 or 6 tries.  Problem, as
    Guignot pointed, was with reference counting.  Should be ok now, all
    affected modules were fixed.
* The Scene module is now "complete" (= 2.25).
* Made some necessary updates to Object and NMesh.
