Implement OPTIONS menu.

Implement options that will allow the user to:

	- rename ftp and ftpd to kftp and kftpd
	- rename telnet and telnetd to ktelnet and ktelnetd
	- rename rlogin to krlogin
	- rename rsh to krsh
	- rename rcp to krcp

This avoids shadowing by or being shadowed by, depending on one's PATH,
system utilities of the same name.
