Clean up deprecated arguments

[vsupalov]

Close #300.

There is a bit of uncertainty. I'm not sure if I understood your intention with deprecating the sitemap flag - my guess is, that the functionality is intended be removed.

If that interpretation is correct, I will add some refactoring to the PR, to make sure the now-unnecessary sitemap related remnants are cleaned up.

Thank you for the changes! I'm gonna review this soon.
