[improvement] Open SAVE AS window when selecting SAVE if the name is UNTITLED.
i think that is necessary to choice a name project when saving (only when saving!) ... saving a project as "untitled" by default can make an involuntary overwriting (maybe after some days .. maybe trying some example and saving it) of it.
P.S. i love that Kdenlive doens't require to create a new project .. with a name/resolution ad other thing, that is usable from the first second after opening app, please not add something like that to solve the issue :)
