Passing!

Openruko is on Travis now! See https://travis-ci.org/tombh/chef-openruko

Though the repo is on my github account it's using only Openruko repos for the actual build, so this is a bonafide Openruko test pass :)

Shall I merge this in then? And change its name (to chef-openruko)? It's a pretty major departure from vagrant-openruko, the main thing is stripping out almost everything from the Vagrantfile and using vagrant only to trigger a more universal [bootstrap.sh](https://github.com/tombh/chef-openruko/blob/master/bootstrap.sh) script, which can be run on vagrant, a VPS and Travis.

Another cool feature is locking down Openruko's dependencies to specific hash revisions, see [solo.json](https://github.com/tombh/chef-openruko/blob/master/solo.json)
