Updating the gnome-software-development group in comps

[Matthias Clasen]

I recently noticed that the gnome-software-development group in comps
has some things in the default install that should probably be relegated
to optional nowadays:

eel2-devel
libgnomeprintui22-devel
libart_lgpl-devel

are the immediate candidates. 
And glade2 should probably be replaced by glade3. 

If nobody objects violently, I'll make these changes later this week.
