CSPACE-2323, CSPACE-3016, etc., Fixes to properly integrate with new Nuxeo libs, making code clean w.r.t. sessions, fixes to hierarchy handling in authorities.
Changed logging configuration to rotate among 10 files of 5MB each, so we have more context on the server. Also removed the stdout copy that was bloating catalina.out (on 1.13 QA, the file is over 1.1GB).
Added new tests to exercise refObjs and authRefs more carefully.
Tweaked XMLReplay to output clock times for each test, making it easier to align tests with log output.
Added some debug support for startup issues with Nuxeo and Workspaces.
Removed pointless output from LoanoutValidatorHandler.
