Remove badly imported libraries.  opensocial is unused, openid and simplejson work fine with newer stock libraries (and leaving them here causes the yahoo library to stomp installations of more recent, better versions).
Move the not-derived-from oauthlib into the yahoo directory, so it's part of the package's namespace, and cannot break an existing oauthlib install.
Fix setup.py to use requirements instead of copied source trees and bump version
