V4.1-beta-2

Second beta release prior to release 4.1

Fixed a couple bugs. One in advisor related to how dates are handled. So changed all date parsing to use the pattern matching and created date formats. Also added Junit tests to check each format works and a performance test case comparing 1,000,000 calls using pattern matching and a fixed date format. Second bug seemed to prevent window synchronisation from working. The key thread was being conditionally created - and I've no idea why. Removed the condition so now always created and synch from window works once again
