fixed bug #2144358 "Double check with 'save as'". The GUI used to
ask twice if user wants to overwrite the file in Save As operation
if file with given name already existed.
* FWWindow.cpp (FWWindow::projectWindowClosed): fixed bug #2144114
"fwbuilder * exits if the last object file is closed". The GUI
will not terminate after the last window is closed but instead
will just show empty main window.
* fwbedit.cpp (main): fixed bug #2143894: "fwbedit list does not
show objects". Command "fwbedit list -f file" did not print
anything unless option "-F" was supplied. This change adds default
value for this option so that when it is missing, the command
prints object path.
* fwbedit.1: fixed bug #2143961: a typo in the man page fwbedit.1
