Adding short stack traces as an option

Updated the package to include a command line option that allows the user to specify whether or not they would like single line stack traces upon step failure.

Currently the stack traces that are output by the package in the event of a step failure are pretty large and make it a little more difficult to see what has failed. The changes I have made cut this trace down to a single line and shows only the line in the code that caused the step to fail.

The changes involved slight modifications to runtime, configuration, argument parser and step_definition.

I believe this addition would benefit others as it seems this issue has been flagged already.
