installing 2012.10

[Kyle]

I'm not sure that Orca is working properly on 12.10's login screen. I 
could drop it into VirtualBox, but I'll need to download it first.

Ubuntu 12.10 will install Unity by default, which has problems with 
Orca. However, Sonar has a modified installer that will fully install 
GNOME 3.6 either with or without gnome-shell, depending on the image you 
download, and configure it to run by default. I'm not 100% sure that 
Orca speaks the login screen on Sonar, but it should as far as I know.
