[Portland] Wrapper scripts

zhrenxi

Very nice!
And here's another one; xdg-menu; creates or deletes
a menu .desktop file on any system compliant with the XDG
menu specification.
If we get xdg-email, xdg-screensaver, xdg-su, we'll have
all of the 'Short Term Tasks' covered (although we need
to expand xdg-mime to allow for the registration of mime types).
I have lots of implementation thoughts on this
(things like do the kfmclient calls return error codes
that we should propogate) but that can be worked out.
We may want to give a bit of thought to name spacing
and calling conventions before we do a first cut; but
we could conceivably ship something useful Real Soon Now (TM).
Cheers,
Jeremy
