Silly mistake

Not sure how the acceptance tests didn't catch this...

```
There are errors in the configuration of this machine. Please fix
the following errors and try again:

Vagrant:
* Unknown configuration section 'puppet'.
```

Should be puppet_install for the config section! :-1:
Use the latest version of Vagrant for testing
Use Vagrant cloud urls for testing boxes
Puppet install uses shell...

Need to add an option to give a provider maybe...
Fix acceptance test issues...

Need to give individual configs, not just a whole global one
Bump version
