big renaming of hive->worker, analysis_job->job, analysis_job_file->job_file, analysis_job_id->job_id, worker.beekeeper->worker.meadow_type, etc

job_error table now holds jobs' termination messages; workers do not die when jobs die, but can be instructed to to so

Added get_available_adaptors to get the pairs of name / adaptor modules. This should make it easier to read etc

Bio::EnsEMBL::DBSQL::DBAdaptor to match symetry with core,pipeline,compara
This means I can remove all 'hive' adaptors from compara now and the
URLFactory now returns by default a Hive::DBSQL::DBAdaptor.
This also means I can make my graph configuring runnableDBs really
adaptible to run on both Pipeline and Hive systems by doing
if($self->db->isa('Bio::EnsEMBL::Pipeline::DBAdaptor')) {...}
if($self->db->isa('Bio::EnsEMBL::Hive::DBAdaptor')) {...}
