Do not tell our users to enable JPA since JPA has too many issues to work stable

We should not have steps/walkthroughs in the docs that says you should enable JPA in the seam web project wizard since we have received alot of issues about Dali/JPA which we do not have control over.

It is not enabled by default for a reason so lets not enable it via the docs.

p.s. it should be ok to enable it on a project after the wizard have been executed via Facet properties, but not during the wizard since the JPA facet conflicts with our current Seam facet.

p.p.s Im not sure if I chose all the right components so please check if they are the only place its mentioned ,)
