Implement profile="XX.XX" on tools, better defaults for newer tools.

 - set -e in tool command scripts.
 - Disable implicit extra file collection. All dynamic extra file collection requires a <discover_datasets tag.
 - Disable format="input" - require explicit metadata targets (metadata_source, format_source).
 - Disable interpreter= - hacky and doesn't work as expected in too many circumstances. Use $__tool_directory__.
 - Disable $param_file - grepping the command for the string is impercise. If useful we can add flag to match the flag used to produce inputs as a JSON file.
 - Disable default version of 1.0.0, the IUC has made it clear they prefer all tools have an explicit version.

Fixes #1609.
