Vagrant upgrade with a little bit of email noise

Simplified Vagrant bootstrapping. Now the box is completely set up in Vagrant and ready to go from launch. Ruby 2.1.3 is pre-installed as well to prepare for our eventual upgrade. The database is preloaded with migrations and seeds. There is a command to run the entire application from the host in one command.
