Add the ability to modify /etc/ttys before first reboot during the

system installation process.  This allows users installing via serial
console to enable serial console login during the installation
process using an un-customized install.  The user is not prompted to
modify /etc/ttys during a normal install, but is offered the
opportunity during post-install configuration.

- Introduce configTTYs(), which describes the benefits of editing
  /etc/ttys, and asks for confirmation before spawning the editor.
- add configTTYs to the post-install configuration, as well as to
  the global configuration index.
