full support for JPA 2.0 PersistenceUnitInfo SPI (for compatibility with Hibernate 3.5 beta 3; SPR-6408)

RESOLVED - issue SPR-6666: CronTrigger/CronSequenceGenerator fails to handle daylight saving timezone changes

SPR-6644 The 'id' value from an 'executor' element in the task namespace is now used as the thread name prefix for the resulting ThreadPoolTaskExecutor instance.

refactored to pass along original ServletContext (for WebLogic and Resin JSP compatibility; SPR-6606)
