Include updated demo space in Confluence 2.10

Sarah and Bill are in the process of making changes to the demo space for 2.10. Bill is trying to get final content by 29 October, in order to have it reviewed by Sarah in the following week.

We need to ensure we bundle their changes in the 2.10 release. I believe it was automated for 2.9, but we need to make sure and quickly test the new space by doing a fresh installation.
