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.
My concern is that it's entirely possible the user has two different git versions between the host and guest and if the host is Windows, then we have all this line ending stuff to deal with amongst other things. I just don't know what complications this can create. I think it's better to cover this in the docs and maybe have a check in the provision script that errors out if the submodules aren't fleshed out.

However, I thought we were doing peep stuff in which case this is all moot.
