Include gnome-orca by default for blind or vision impaired users

Because access to the desktop by blind or vision impaired people is very important on any operating system, both for installation and daily use, and because the gnome-orca package is officially included as part of a complete GNOME install, the inclusion of gnome-orca by default, both in the live CD/DVD and in a fresh installation of Linux Mint should be considered. At present, a vision impaired user has to start the live CD/DVD and then install gnome-orca using apt, trusting that it worked. At this point, gnome-orca must be started and setup, which then requires logging out and back in to set the assistive technology features in GNOME. Then, after installation, the user must again install gnome-orca and perform the same procedure in order to make the newly installed Mint system fully functional with speech or Braille output. I am proposing that the assistive technology features be enabled at boot time from the live CD/DVD with a keystroke, and that this setting should carry over into the new installation, in addition to gnome-orca being included in the default package set that is installed both on live media and after a fresh installation is completed.
