differentiate cvl desktops from huygens desktops
Merge branch 'master' of https://github.com/CVL-dev/cvl-fabric-launcher
temporary keys now avoid using the system ssh agent (otherwise you migth log in without password even if you really wanted to use a password)
Another fix to misformating in the dialog asking if you want to stop the desktop
make sure that the modal HelpDialog displaying an error message completes before the rest of the shutdown process is called, otherwise we get two modal dialogs at once
