Please cherry-pick:

Please cherry-pick:
- rewrite of almost all beans towards more cleanness
- now fields in backing beans can be "only" be set by JSF views or observer
  methods
- removed @Local from interfaces, they are already local and maybe that
  annotation is for EJBs only?
- passing beanHelper.fooBar over a JSF view to a backing bean is not needed,
  the bean can do it by itself, by CDI

- fixed tpzo
