point to snazzy new box

I made a box. It's small (relatively: 421M). This fixes #4.

test run from scratch:
```

$ vagrant up

the provider 'virtualbox'. Note that if the URL does not have
a box for this provider, you should interrupt Vagrant now and add
the box yourself. Otherwise Vagrant will attempt to download the
full box prior to discovering this error.

[default] The guest additions on this VM do not match the installed version of
VirtualBox! In most cases this is fine, but in rare cases it can
prevent things such as shared folders from working properly. If you see
shared folder errors, please make sure the guest additions within the
virtual machine match the version of VirtualBox you have installed on
your host and reload your VM.
