Update vagrant file

[ElectricMaxxx]

tried to run a vagrant up for the sandbox and got the following error:

There were warnings and/or errors while loading your Vagrantfile
for the machine 'default'.

Your Vagrantfile was written for an earlier version of Vagrant,
and while Vagrant does the best it can to remain backwards
compatible, there are some cases where things have changed
significantly enough to warrant a message. These messages are
shown below.

Warnings:
* `config.vm.customize` calls are VirtualBox-specific. If you're
using any other provider, you'll have to use config.vm.provider in a
v2 configuration block.
* The 'v-root' shared folders have been renamed to 'vagrant-root'.
Assuming you meant 'vagrant-root'...

and

It appears your machine doesn't support NFS, or there is not an
adapter to enable NFS on this machine for Vagrant. Please verify
that `nfsd` is installed on your machine, and try again. If you're
on Windows, NFS isn't supported. If the problem persists, please
contact Vagrant support.

think the second on is an issue on my machine. But the first is an update issue. Somebody time to fix that?

i guess it would make sense to upgrade the config to the new version of vagrant. but these are just warnings so it would start anyways.

i think the real problem that is preventing you from starting the vagrant box is that you don't have nfs support. you should install that or change to a different filesystem method like rsync (but then not commit the file to avoid problems for others).

indeed the vagrant setup needs some love #266
