Universal install script (From Xwiki hangouts meet 8)

I feel that if we set our sights low and simple for the first we should be able to slowly extend the script at a manageable pace, we could even start the very first one off as with @tmortagne 's suggestion of a simply jetty+xwiki

A sound plan! I am not sure who would be the webadmin/forum admin? so we could perhaps start putting some ground work into such a solution, I am actually hoping to do an experimental first youtube walk through when I figure out howto get my ideal setup Here
