Use the current filename. If there is no current filename do what you
think is better, either show save as dialog or ignore the signal. Other
possibility is to allow supply of non-existent file path to be used for
first save in the app. Better make it non-default behaviour because it
is somewhat strange if you dont use ladish. I.e. user usually expects
start to fail if project file supplied at commandline does not exist.
