Change the git source for spacemacs so it links up with the existing git source.
Also remove the spacemacs dotfile, this will be in the private repo until I can
sort out a private spacemacs module to put some stuff
This is the first commit that brings the privet dotfiles to a public
reop previously this was all one puppet module. Now this has been split
out so I can put all of the private files in a private puppet module
