Update of 4 docs from Getting Started branch

[F Campos Costero]

I just pushed my first revision of the first four sub documents of the
Getting Started Guide (AOO41GS1 - AOO41GS4). I have not made a pull request
yet. Since this is a new process for everyone, I thought Keith, Marcia or
someone else might want an early look. I only turned on Record Changes for
GS3 and GS4. Sorry! The biggest change was incorporation of the Sidebar in
AOO41GS2 and Jean did almost all of that.
All comments welcome!
