Inserts get done even when flushmode == manual and they are not necessary

         Environment: Hibernate 3.2.3, HBEM 3.3.1, Tomcat 6.0.10, PostgresSQL 8.2, Seam 2.0.0B1

When the flushmode is manual (and in many other cases too) Hibernate should not do an insert when persist() gets called. The current code always forces an insert when a record is persist()ed with generated keys, even if the generator can be used without the insert. This causes trouble when an insert is used in seam's long running conversations (and when an entity is persisted while not all of it's fields have valid data - nullity etc).

The problem is caused by a few problems in passing around a boolean requiresImmediateIdAccess) which gets set to true always in some calls. A fix which prevents Hibernate from doing the insert is attached.
