Add vagrant

Add a Vagrant configuration and provisioning via Ansible.

Spools up a VM with a generated wrapper application, Marmotta, and Solr.

Includes Redis.

The instructions in the README describe what to do.

I've always preferred to forego port-forwarding, and connecting to the VM as a separate host, as in 'http://krikri:3000/' or whatever.

On another note, I'll change the variable name `qt` to `krikri`.
