Doc: Resizing Boot2Docker Volume with VirtualBox

The Boot2Docker VM ships with a 20G VMDK volume, which can quickly fill up if one is using large images/large numbers of images. This is a step-by-step guide for increasing the B2D volume using VirtualBox and GParted.
I don't really agree - if its an application, then many people will expect to install and run it as such. What this is doing, is booting the VM with a GParted CD - and confirming to the user that they are indeed booting a virtual CD should help it be a tad less scary.
