Update phpunit, mockery and boris composer packages
Add wildcard Nginx rules to load default VVV domains via xip.io

local.wordpress.*.xip.io
local.wordpress-trunk.*.xip.io
src.wordpress-develop.*.xip.io
build.wordpress-develop.*.xip.io
where * represents an IP address

The goal of these rules is to allow other devices on your network to
load these websites using URLs like the following
local.wordpress.192.168.1.10.xip.io
local.wordpress.10.0.1.20.xip.io

Install the mainline version of Nginx

In the world of Nginx, mainline can be considered the most feature
rich and the most stable. The "stable" release receives only bug
updates. A good explanation of this was posted by the nginx project
after the initial 1.7.x release from 1.6.x

http://nginx.com/blog/nginx-1-6-1-7-released/

I've used nginx 1.7.x in production since that day and have not had
any troubles. I think we should be good to move to mainline as our
default provisioning.

Add wildcard Nginx rules to load default VVV domains via xip.io
Add network config info for host local IP address

By default, the guest machine is accessed by the host machine via
192.168.50.4.  Instead, we want to make the guest machine accessible
from the host machine's IP address.  This will allow us to access the
guest machine from other devices on the network (e.g. a smart phone)
change network setting to local IP:8080

Change guest machine network IP to host local IP on port 8080
update default page urls to xip.io
add port forwarding commands as vagrant triggers

When running on your host machine's local IP address it is
necessary to port forward 80 to 8080.  (When assigning a port to your
guest machine it must be larger than 1024, therefore we port forward
on the host machine so we can use the appropriate port).
Rather than setup and remove port forwarding
each time, I've added the commands as vagrant triggers.

Note: this requires the Vagrant triggers add-on to be in place
