Create a neat CLI with the help of boost::program_options

[HerrHorizontal]

This replaces the outdated draft for an CLI with the help of the functionalities provided by Boost.Program_options.

@HerrHorizontal thanks for this CLI, looks good!

Maybe we can also think of outsourcing that to a separate header to avoid too large merge-conflicts.

On the other hand, there is a good overview over the changes made, so I think we can merge the pull request now and see what happens if merging into wrench 2.0 branch.

I think the old hacky-wrench simulator is finalized with this PR. So there is no need for substancial changes. For Wrench2.0 I plan to cherry-pick the merge commit.
