Add porters-handbook for USE_GNOME.

This contains two chapters. The first chapter explains USE_GNOME and
the macro's and the second chapter which lists all the possible
components with a short description.

Loosely based on the old porting guide (http://freebsd.org/gnome) and
the Qt chapter. The old porting guide will stick around for now until
I get around to updating the gnome website.
