Add Vagrant for easy reproducible server dev environment setup

To start a dev VM do `vagrant up`
You'll have the RECAP server running on 10.42.42.42:8000
Config: Database recap_dev - User recapper - Pass recap
It will run directly your codebase, and log in your debug.log
Access the output of the server from root's screen via `vagrant ssh`

I plan to add also a PhpMyAdmin to the mix.
