Moved the caching from Hive.pm into the specific storable classes themselves (via Cacheable.pm) to better conform to Active Record pattern

storing "synchronized" analyses means we don't need to adjust counters when storing jobs ; generate_graph -pipeconfig gets correct counts

computational part of sync() moved into AnalysisStats::recalculate_from_job_counts and can be run separately

no need to update only the status here, as we are going to update the whole AnalysisStats object very soon.

check_blocking_control_rules() no longer talks to the adaptor, it gets its rules from analysis->control_rules_collection

decomposed HiveGeneric_conf::run into more manageable parts; hive_meta & pipeline_wide_parameters now also cached

Graph.pm uses cache collections (no change in interface) ; A.control_rules_collection and A.dataflow_rules_collection lazy-load from collections

start using Hive.pm for global storage of collections; Storable first checks these collections, then resorts to fetching
