Ugh, don't start with this one. Menu editing is actually quite complex
and will only get you frustrated unless you know what you're doing. I'd
suggest to wait with it until garcon, the rewrite of libxfce4menu,
matures and gains a menu editing API which will allow you to implement
this feature with a few lines of code.

The correct signal for right clicks should be the 'button-press-event'
signal of the GtkMenuItem that is created based on XfceMenuItems in
xfdesktop/modules/menu/desktop-menu.c.

http://standards.freedesktop.org/menu-spec/menu-spec-latest.html - this
is where the menu format is defined. Again, it's relatively complex and
you might want to start with something easier.
