I modified the Makefile and added a virt-builder config so that a RHEL7.0 could be build
selinux is default for docker and should be used
used the versions/...sh build pattern for rhel7, added up to date epel and puppet reops
This is just related to RHEL7.
this was just a demo file
Cleanup Goern's patches so that the public default is CentOS.

Building of a RHEL7 image should be easy by adding a versions/ .sh file.
