PyKeyingSet Bugfixes:

* With multiple objects selected, only one of the objects got keyframed. The code which was checking for duplicate paths was wrongly assuming to ignore the ID-block used still.

* Not registering a Keying Set as 'builtin' would crash on startup. I've made all Keying Sets fallback to adding as if they were local for now, but a better solution is coming soon.

* Fixed a typo in RNA function wrappers for the generator callback, since it was looking for the iterator only. This doesn't seem to have caused any problems (thankfully).
