This is a first crude attempt at allowing reloading without exiting
fped. This should be useful when writing a design as text and using
the GUI only to visualize it.
Reload is only enabled (in the File menu) if the file doesn't have
the "MACHINE-GENERATED" header.
Known bugs:
- exits on parse errors
- leaks memory badly
- current frame is reset to root
created file. This is a precaution against accidently saving to a manual work,
which would change the structure and remove all comments.
- fped.h, fped.c, file.c: moved declaration of save_file_name into shared
header
- dump.h, dump.c (MACHINE_GENERATED): moved header marking machine-generated
files into shared macro
- gui.c (save_as_fpd): added "Save as" dialog
- fped.h, fped.c (load_file), gui.c: disable "Save" if editing a file that
doesn't have the machine-generated header
