Improve first run project setup

[jason-o-matic]

The tests depend on vagrant and virtualbox, but they weren't specified in script/setup so you couldn't run the tests immediately after setup.

This also fixes an error with the initial bundle install:

[master] instrumentald $ ./script/setup
Fetching gem metadata from https://rubygems.org/.......
Fetching version metadata from https://rubygems.org/..
Fetching dependency metadata from https://rubygems.org/.
Resolving dependencies........
Your lockfile was created by an old Bundler that left some things out.
You can fix this by adding the missing gems to your Gemfile, running
bundle install, and then removing the gems from your Gemfile.
The missing gems are:
* CFPropertyList depended upon by facter
* CFPropertyList depended upon by puppet
…
fatal: No live threads left. Deadlock?

`pop'

Unfortunately, an unexpected error occurred, and Bundler cannot
continue.

Adding CFPropertyList to the gemfile fixes this. Contrary to the directions, then removing the gems doesn't work, so it stays for now.

:+1: much smoother for future Nate.

I had some verify failures with puppet, but, no more than I did previously... I'll investigate.

(the things that are still broken are fixed in #65)
