Add SCL packages for OpenShift_ 

Erik,
I have added EPEL 6 repos and an ungodly number of packages pulled from the RedHat Source Code Collections to support OpenShift. 

I have included, but not yet tested:
- perl516
- maria55

and some of the ruby 193 modules don't build yet. But python 33, 27, node, most of ruby (enough for us at the moment), postgres, and mysql all cook up fine via mock.
