Desktop spin size update

[Matthias Clasen]

A quick update on the size of the desktop spin:

I have written a patch to split libgweather into a bazillion langpacks,
you can see it here: 

http://people.redhat.com/mclasen/split-libgweather.patch 
http://people.redhat.com/mclasen/comps-libgweather.patch

I am not entirely happy with this approach, but it certainly solves the
size problem. An x86_64 iso that I build with that reduced libgweather
came at 692M. What I don't like about it:

- It creates some 80 new packages
- Some langpacks don't have a matching lang support group in comps


There is a number of other pending changes that should give us some
space back:

- drop libsexy: https://bugzilla.redhat.com/show_bug.cgi?id=509299
- drop ImageMagick: https://bugzilla.redhat.com/show_bug.cgi?id=472103
- drop esound-libs: https://bugzilla.redhat.com/show_bug.cgi?id=492982
- drop some big unneeded files from packages:
   https://bugzilla.redhat.com/show_bug.cgi?id=512502
   https://bugzilla.redhat.com/show_bug.cgi?id=463773
- complete the PolicyKit 1 ports and drop PolicyKit 0.9
- drop gst-mixer again
- maybe drop krb5-auth-dialog
