Use skel as the source of new user files rather than copying from root.

remove the command number shown in the shell prompt, it's a pointless
waste of screen space

Add nonewline to end of file to avoid issues when new options are added

Don't force/hardcode background color in terminal. See http://forum.pfsense.org/index.php/topic,61131.0.html

Fixup home/end/ins/del in shell.

Move the skel dir to /etc/skel, where it's easier to manage from a build point of view.
