YAHRF (Yet Another Hive ReFactor).....chapter 1
needed to better manage the hive system's load on the database housing all the hive related tables (in case the database is overloaded by multiple users). Added analysis_stats.sync_lock column (and correspondly in Object and Adaptor) Added Queen::safe_synchronize_AnalysisStats method which wraps over the synchronize_AnalysisStats method and does various checks and locks to ensure that only one worker is trying to do a 'synchronize' on a given analysis at any given moment. Cleaned up API between Queen/Worker so that worker only talks directly to the Queen, rather than getting the underlying database adaptor. Added analysis_job columns runtime_msec, query_count to provide more data on how the jobs hammer a database (queries/sec).
