Please rename/cherry-pick:
- having to much session-scoped beans was a bad design idea anyway
- on each new session, "tons" of EJB (JNDI lookup + business method invocation)
  will occur which will overrun the EJB container soon or later
- also having JNDI lookup in PostConstruct-annotated methods was bad, too
  because it "confuses" the web container
- while it is building proxy objects arround every managed class (like also now
  converters, JSF 2.3.x only) especially backing beans, there should be no JNDI
  lookup hapening
- but initializing some lists for performance reasons is the right thing to do
- maybe later some other annotation will be used instead, but for now it is fine
- so let's make this painless and rename all session-scoped backing beans and
  re-annotate them with RequestScoped for now as this is also reduces memory
  foot-print
