First batch of fixes for non-existent packages
    
    There are a lot of comps entries pointing to packages that just
    don't exist any more. Note that group installs don't follow
    Provides: or Obsoletes: or any of that jazz, the package must
    exist under the exact name listed in comps.
    
    This is a first set of fix-ups for these (as I've been working
    on it all afternoon and am tired now). I looked into the reason
    why every single one does not exist any more. Some had obvious
    replacements, so I used them. Some did not, so I just took them
    out. These are all packages that no longer exist on *any* arch,
    I'm dealing with the 'package exists on only some arches' entries
    later.
