Added $HOME variables for AWS vagrant deployment

@fideloper I have updated some features for your Vaprobash.  I updated the Vagrantfile template to allow a developer to deploy to an AWS ECE instance.  This uses the aws-plugin for vagrant.

In order to make this work, I had to modify some of the scripts such that all /home/vagrant to $HOME.  In addition, I had to change a gist reference in the nodejs.sh script to refer to my just for the same reason.  Maybe we might want to consolidate this just into the repo itself as a self-contained file.

I have also implemented in the base.sh a way to create a 1G swap disk.  I have found when creating an instance, we can run out of memory and the mysql databases crashes, which is a known issue.

Let me know your thoughts!
