Implement handler for cancel button of Save As dialog

Browse source 
When an user opened the "Save as" dialog and pressed the
cancel button a null string was returned. Therefore the
file_save_as function returned an error which was lately
shown when the file_save function was called.
Now the function checks if the cancel/exit button was
pressed and returns.

Fixes #844
