[jbosscache-dev] Docs changes

I made a bunch of changes to the JBoss Cache User Guide last week, mostly in the Configuration and Deployment sections. Any comments/edits/etc will be most appreciated. One suggestion I have is to move the User API chapter before the Configuration chapter. For the User API chapter you don't really need to understand the Configuration; a couple simple hyperlinked "for more on this Configuration stuff see the Configuration chapter" sentences are sufficient. With User API before Configuration IMHO you get a more understandable flow: 1) Intro -- what it is 2) User API. -- basics of using it, making clearer what it is 3) Configuration -- going deeper 4) Deployment -- closely related to Configuration -- Brian Stansberry Lead, AS Clustering JBoss, a division of Red Hat brian.stansberry(a)redhat.com
