Adding packages to ubuntu-desktop packageset

[Alessandro Astone]

Hey there.

As a member of ubuntu-desktop, but not a core-dev, I find it hard to 
actually maintain the desktop because multiple packages are not in the 
packageset. I have gathered a list of packages over the last couple of 
weeks, which I've organized below by category.

Some of these I found to be already part of the desktop-core packageset, 
which however doesn't seem to have any uploaders which makes me wonder 
why it exists.

Please consider the following packages for inclusion in the 
ubuntu-desktop packageset:

=GNOME=
glycin
gnome-kiosk
gnome-shell-extensions
gnome-terminal
loupe
showtime
