Getting started with the 12.04 Documentation Stable Release Update

[Jack Fromm]

Progress update:

I have gone through Chapters 2, 3 and 4 (migrating-upgrading.xml, 
guide-desktop.xml and guide-default-apps.xml) and submitted a merge 
proposal for them.
I'm going to move on to Chapter 5, (media-apps.xml) unless somebody else 
has already started on that.
As I mentioned earlier, I don't think the Intro and Chapter 1 (intro.xml 
and what-is-xubuntu.xml) need any changes.
