Initial commit
README.md: add some getting started stuff
README: point at using coreos

Point at the Using CoreOS guide instead of replicating those docs in
this readme
Ignore vagrant directory in git.
Alternative setup for vagrant without needing to clone

Additional information for getting vagrant up and running without cloning the repo.
Remove step three
improved vagrant installation instructions - and included virtualbox

I noticed the installation instructions on the website and this repository do not mention Virtualbox at all and make it sound like CoreOS runs *on* Vagrant. This confused me at first.

With this rewrite I hope to make it more clear how it actually works. I would also hope to see some to this effect on the http://coreos.com/docs/vagrant/ page.
