Snapshot of python-skeletons @ 983e594
Read skeletons from the config and 'helpers' directories only
Fixed checking 'int' against comparison operators in structural type

Previosly we collected only atttributes defined in the class and its
ancestors. Now we collect attributes defined by class members providers
as well. Since comparison operators for 'int' in Python 2 are defined
in user skeletons, they used to be unavailable for the attributes
search.
