Add vagrant files
Add pillar env state
Fix nginx state deps
Use bind_url from env for nginx site
Refactor slingsby state
Install mysql server on vagrant
Don't run newrelic on vagrant
Remove grunt-concurrent

Was mostly just confusing and bugprone to run the devserver and the tasks
in the same tasks, especially if the devserver crashed and you needed to
restart the watch task as well to get it going again.

New solution, just run the devserver in one terminal, and watch in
another.
Remove ntnuita.no as host for devserver
Refactor and make it work under vagrant
Refactor memcached state
Update and clarify readme
Add default pillar/secure/init.sls
Merge pull request #35 from thusoy/vagrant-rebase

Add vagrant.

You can now run pretty much an exact copy of the server locally, to test how they will be on the server.

All you need to do: `vagrant up` (starts the vm). ssh in with `ssh vagrant@localhost -p 2222` (or just `vagrant ssh`).
