Adding MuukReport to mkcli for a better error reporting.

[jesus-serranop]

Summary of the problem/fix:
mkcli is not returning enough information when an execution fails. With this change, mkcli will return new muukReport containing step by step information (selector, part of the DOM, stepCompleted, exceptions, step type, etc).

Tests executed:
mkcli with failed and successfully test executions.
