Vagrant 905834

This adds an option to deploy kitsune via Vagrant with Ubuntu 14.04. 

* ./manage.py generatedata does not currently work, not sure why. Was planning on using an anonymized dump of the production database for data.
* Also, this is blocked until the requirements update in #1984 is merged as well.
This installs 0.90.13, which matches what I had on my laptop when I was helping Dean set this up. I guess I'm not on the right version either :\
