[FFe] New screenshots for installer slideshow in Ubuntu 12.10

[Dylan McCall]

Hi! Just a little freeze exception notification :)
https://bugs.launchpad.net/ubuntu/+source/ubiquity-slideshow-ubuntu/+bug/1064232

This freeze exception request is for an update to
ubiquity-slideshow-ubuntu that will add some new screenshots. The
screenshots until now have been of Ubuntu 12.04, so there are some
subtle inconsistencies in comparison to 12.10. This brings everything
in line.

A preview with the new screenshots in action is available over here:
http://www.dylanmccall.com/static/ubiquity-slideshow/ubuntu/slides/index.html?#controls=true&locale=en_US

Total size of the ubuntu screenshots directory before update: 482.5 kB
After update: 506.1 kB

No string changes, so this should only really affect anyone if you
have a screenshot of the slideshow or you're referring directly to one
of its screenshots.

Thank you,
Dylan
