use provisioner-less baseboxes
[COOK-2866] - use python binary vs existing directory
[COOK-3008] - update source install to 2.7.5
[COOK-3009] - Add packages, build flags

We need additional packages to ensure all the proper dependencies are
available for python to build and distribute to install properly.

Also, we need to tell newer Ubuntu (12.04+) to look for them in
/usr/lib.
pull ubuntu 13.04 for now, not yet in omnibus install.sh
release v1.3.0
increment version for development
