I made a patch removing all gnome dependencies for devhelp

[Kristof Vansant <de_lupus pandora be>]

http://bugzilla.gnome.org/show_bug.cgi?id=167213


Can someone please review this patch?

patch:
- updated autogen.sh the old script did not build on my system. This one
will work with newer automake versions :)
- configure.in does not look for gnomeui anymore
- #include <libgnome/gnome-i18n.h> replaced with +#include
<glib/gi18n.h>
- poptOption replaced with GOptionEntry
- use gtk_init
- gnome_about replaced with gtk_show_about_dialog
- devhelp now needs gtk+ >= 2.6
