Adding a new functionality (CLI only for the time being) of simulating respondents responses directly from a CSV file and producing a CSV on the output. This will, most likely, cause a deprecation of the gmnl_2a/simulator code (it is retained currently... but only just) which works with a lower-level bulk_msg files/objects.
CLI-based regressions and fixes thereof.

(*) regression formatting-bug w.r.t. newlines when a new task is being submitted via the CLI controller (feedback_string et. al.)

(*) regression bug in controller_xxx.sh scripts -- was missing a, subsequently introduced, mandatory option for "--short_description"
WebNetCPU -- introduced whitespace wrapping in the "pre" HTML elements.
