gnome-desktop and workstation-product comps deduplication

[Michael Catanzaro]

Hi,

I spent some time with F24 comps tonight, removing a bunch of packages
from gnome-desktop that we don't ship in Workstation, and removing
GNOME packages from workstation-product, then included gnome-desktop in
workstation-product-environment. If I didn't make any mistakes then
there should be no changes to what gets installed... but if you find
something does break, please revert it or fix it or let me know.

This solves the problem of having two big lists of GNOME apps, one
unmaintained yet an inviting place to add more GNOME apps, so it should
reduce future accidents where gnome-desktop gets edited by mistake
(remember that caused us to accidentally release F21 without Maps).
Going forward, you really do want to add GNOME stuff there once again.

I didn't touch F23.

Michael
