ResourceDescription expanded to include both submission_cmd_args and worker_cmd_args. Both args can be specified in a PipeConfig file.

(1) do not change SEMAPHORED jobs to READY and (2) support more flexibility in choosing which statuses to reset

schema change: turned all VARCHAR(<255) into VARCHAR(255) -- should improve experience with long host namest (thanks, MichaelP!)

param_required() now automatically sets transient_error(0) before dying, to avoid unnecessary retries (thanks, Matthieu!)

pipeline_name is now automatically computed from ClassName; simplified workshop's example files and slides

cleaned up the last (optional) slide on pipeline_wide_parameters; removed the exercise about abstracting out the compressor (formerly from CompressFiles_conf)

separated out "long addition" functionality to concentrate on Hive API when writing the Runnable, and not on maths

bugfix: ENSCOMPARASW-132. When all dependent jobs (>1) fail to be created due to unique constraint, they now correctly update status to READY

bugfix: reset the tried jobs to retry_count=1 and untried ones to retry_count=0 when doing a bulk reset
