Using a 'box' that we build instead of having to build the world from scratch

I took this blog post:
http://abhishek-tiwari.com/hacking/creating-a-new-vagrant-base-box-from-an-existing-vm

Made a few modifications to our VM build so it didn't import the initial sites (assets, cms, etc) and built an OS box that has everything we need installed and ready for sites to be imported.

I also kept the 'Vagrantfile.box' so we have a copy of how the box was created. We may have to come up with a separate branch or something to manage creating a new/updating this box after a few months in case we want to change the software on it.

But basically this reduces the `vagrant up` speed on a fresh box from 20 minutes to 2. :smile:
