- Add rubygem-polyamorous 1.3.0

Polyamorous is an extraction of shared code from the Active Record Hackery gems
Ransack, Squeel and MetaSearch by Ernie Miller and maintained by Ryan Bigg,
Xiang Li, Jon Atack and a great little group of contributors.

It is an internal library for extending various versions of Active Record with
polymorphism. There is no public API, so it's :nodoc:. Move along. Nothing to
see here.
