Add Korea as a partner on the PIT

This PR contains the changes to include Korea as one of the partners. It has been properly tested but cosmetic changes may still occur.

This PR should be the start point of a releases/pit-2015.1.2 branch
@tpolecat would you take a look here?  Discussing it with @cquiroz we weren't sure how to override this to make the p1 model run at a lower start level since Configuration is a case class.  So we ended up just putting it here.
