Dagger 2.13

• Reductions in code size - code for repeated bindings is now placed in private methods instead of duplicating it throughout the component
• dagger.android speed improvements:
  • Avoid calling Class.getCanonicalName(), which is slow on Android, during normal execution (c19f0c2)
• dagger.grpc - update to gRPC 1.8 (19cc9f4)
