Easy setup of DSA stack using vagrant

@brianhelba can we assign this to someone? This will allow everyone to use the same development environment.

This will be a part of the https://github.com/DigitalSlideArchive/digital_slide_archive repo. I'll try to add something basic today.

@brianhelba Ok. Also, can we base it out of ubuntu 16.04 so we can simply apt-get install insight-toolkit4-python and get ITK with python wrapping. We are currently writing functionality in HistomicsTK core which is already available in ITK.

+1 To using 16.04 eventually, as that will fix a lot of the pain we've had with VIPS / and OpenSlide.

However, 16.04 isn't going to be released for another 2 weeks, and it will be a while before everything gets fully migrated to that (e.g. we have to upgrade our own servers and VMs, Vagrant has to release a new image, Travis needs to support it).

So, I'm starting with support for 14.04 because I can adequately test on that right now, but we can add 16.04 as the various pieces come online.

Ok.

Vagrant already seems to have an image for ubuntu 16.04. See this.

According to this TravisCI doesnt plan to support 16.04 this year. They seem to suggest a workaround using Docker.
