Merge pull request #4 from tfhartmann/master

Changing Arch to x86_64 as some things don't support i386
moved things around a bit so that this can be deployed via nepho stack create
Vagrantfile now reads the cloudlet location from the context, instead of assuming CWD. Makes the puppet run work for now (or at least start.
add an external Vagrantfile for invocation when not used through nepho.
