6500: Office 2003 Add-ins: Fix for AWC-1505
   6501: Fix for AWC-1361
   6502: Fixes for locking issues regrading expired content
   6503: Fix for AR-1615

   6505: WCM-498 wasn't fully fixed
   6506: Fix for AWC-1462
   6507: Fix for WCM-741 (link validation report for staging sandbox can get stuck)
   6508: AR-1650: WS Unit tests fail
   6509: Fix for WCM-751 which also solves WCM-570 - also fixed issue to allow deletion of any "broken" webprojects created due to either of those bugs.
   6510: Fix for WCM-546 (workflow history panel should be expanded by default)
   6511: Fix AWC-1128
   6512: Fixes to several to a couple of bugs found under concurrent load.
   6513: Build fix for test using an invalid noderef (now stripped out as it does not exist)
   6514: Add support for the QueryFile transact request to the IPC$ named pipe handler. Fix for AR-1687.
