ACTION-284 - web arch table of contents

Re ACTION-284

"Flesh out the Web Application (
http://www.w3.org/2001/tag/2009/06/webAppsTOC.html ) outline with as
many sentences as he can"

 I did some work of this in prep for the F2F. (Sorry for lateness.) If
y'all could take a quick look before we take up the web app/web arch
topic that would be good.

I was supposed to add sentences and unfortunately have mostly not done
this, so won't consider the action to be pending review yet.

New version is in same place as old.
