- Big refactor of the QuickJournal:

- Move it to it's own package org.apache.activemq.store.quick
  - Brought in all the latest JournalPersistenceAdaptor enhancements
  - It now uses the AsyncDataManager as the Journal implemenation which has better read performance
  - Instead of forcing all PersistenceAdaptors to support external references, we now move all the message reference methods to a new set of interface class (MesageReferenceAdaptor)
  - Enhanced a few Kaha container classes so that they take advantage of Generics
  - Added a Kaha based MesageReferenceAdaptor impementation
  - Strategy for deleting old journal log files is now in place so that disk space can be reclaimed.
