This patch includes the necessary changes to connect ruby objects using the python configuration system. Mainly it consists of removing unnecessary ruby object pointers and connecting the necessary object pointers using the generated param objects. This patch includes the slicc changes necessary to connect generated ruby objects together using the python configuraiton system.
