Rigify: More updates for 2.8 API

With those changes the addon is working in some functional state.
Thus I'm bumping its version to 2.80.

TODOS:
* Handle collections (put all the new objects in a collection).
* We should also replace the old WGT_LAYERS with subcollections.
* Move toolshelf operators out of there (make tools or move to sidebar).
