make sure beekeeper quits when looping in -logic_name XXX mode and there are no more jobs in this analysis -- thanks, Irina!

attempt to re-introduce the Workers that have never specialized and therefore do not have a real analysis_id,
yet have claimed resources and so should influence the stats

Conflicts:
	scripts/generate_timeline.pl

a more correct treatment of resource_class_id (first call is from a specific worker, and then from the analysis)

schema patch_of_a_patch: ignore possible collisions of meta_keys in meta that are no longer tolerated in pipeline_wide_parameters.

schema patch_of_a_patch: Type system in PostgreSQL is really weird, and doesn't allow even explicit cast from DOUBLE PRECISION to NUMERIC

schema patch_of_a_patch: to stop confusion caused by automatic naming of FKeys in MySQL, start giving them names (rest to be fixed in the next official patch)

schema patch_of_a_patch: reconstruct the role table's contents to the best of our ability from corresponding log messages (in MySQL)

api_change: beekeeper passes only the submit_log_dir to the Meadow, which may then decide how to capture submission logs best (thanks, Lel!)

api_change: Runnable/Process no longer caches a reference to Analysis. It can be had via $runnable_object->input_job->analysis if needed.

cosmetic/bugfix: refer to load_resource_usage.pl in usage legend instead of lsf_report.pl that is no longer around
