Command-line parameters

[Patrick Lam]

So, AbiWord supports a number of command line parameters.

One evil thing is that the GTK and GNOME builds actually have different
command-line parameters.

The GNOME command-line parameter handling is kind of convoluted, actually.

But, for instance, we have --nosplash in the GNOME build, and -nosplash in
the GTK build.  I think that we should make this consistent (on other
platforms too, I guess).  I'd like to go with the double-dash format.

What do people think?
