Dragons waiting

This release contains only one API client package, a very quick and dirty version of a client for the waiting list API, and a command line tool for importing new members to a waiting list.

This was first created for Sjöscoutkåren Drakarna so it requires the input csv to be in the format from their old queue system export - this should probably be updated going forward to accept some more alternatives, or at least a more straightforward one.
