in qtSkeleton (backport from Wolframe/qtwizviz and configurator/master):
- removed the NoSSL dialog, WITH_SSL only trigger message boxes when
  no SSL is compiled in and the user tests a connection or tries to
  login securely
- removed QCommandLine parser. The first optional command line argument
  is now the path of the setting file, e. g. 'qtclient configurator.conf'
