this closes #110

I need to understand a bit more why you have arrived at this solution, I definitely need to fix the lock file to add logrus.

It seemed the logrus discussion concluded that i should be using the lower case version.

orgainization/user on github is called Versent not versent. When you click on the 'clone or download' button, the link is Versent as well ... So it is a bit confusing. I think that the names should be consistent.

Yeah I understand the confusion and I will endeavour to fix this in a future change but I am not sure it is critical right now as this is a CLI tool.

I will open another ticket to fix the Versent name in imports.
