Edit Linked Library: Added support for more library types.

In particular, this commit adds support for override libraries on
objects. In the past, if you made an override, Edit Linked Library lost
the reference to the original library. That's fixed now.

Also, in linked Node Groups, this commit also adds support for linked
Sverchok group nodes.
