Remove Skyscape Interim AnyConnect profile

Since moving to Platform 1, we no longer need a VPN to connect to vCloud
Director. Instead, we authenticate through the Skyscape portal, which then
passes through to vCloud Director. As a result, Boxen no longer needs to
configure the Skyscape Interim platform AnyConnect profile as we do not need
to use it.

Split out into install and boxen-upgrade.

Revert "[jabley] Apparently Vagrant DNS is better now"

This reverts commit 01b4de3a621623f09f5d7aa6599f0814538b3449.

Vagrant DNS does not appear to play nicely with multiple VMs. When I try
to spin up pp-puppet, it causes puppet/development VM to crash and vice
versa. I think this is the only thing I've changed recently?
[jabley] tweak which packages are latest

Some don't seem to like being marked as that.
[jabley] install tesseract

Mentioned on #pubstandards and seems useful.

Update VirtualBox to latest release

I was getting a VirtualBox error when importing our latest image.
```
There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["import",
"/Users/bobwalker/.vagrant.d/boxes/govuk_dev_precise64_20140430/0/virtualbox/box.ovf",

I fixed this by updating to the latest version.
