Subject: Make it obvious that some scripts are templates and cannot be used
 as-is.

This affects:
- pxeserver
- setup2hd
Both have been renamed with extension '.tpl' as indication that they are
templates.  The 'make_slackware_live.sh' script performs a series of
substitutions on them to produce the actual scripts inside the ISO.

-
-# PXEserver works as follows:
-# - It requires a wired network; wireless PXE boot is impossible.
-# - The pxeserver script tries to find a wired interface; you can pass an
-#   explicit interfacename as parameter to the script (optional).
-# - If multiple wired interfaces are detected, a dialog asks the user to
-#   select the right one.
-# - A check is done for DHCP configuration of this wired interface;
-#   * If DHCP configuration is found then pxeserver will not start its own
-#     DHCP server and instead will rely on your LAN's DHCP server.
-#   * If no DHCP config is found, the script will ask permission to start
-#     its own internal DHCP server.
-#     Additionally the user will be prompted to configure an IP address for the
-#     network interface and IP range properties for the internal DHCP server.
-# - The script will then start the PXE server, comprising of:
-#   * dnsmasq providing DNS, DHCP and BOOTP;
-#   * NFS and RPC daemons;
-# - The script will detect if you have an outside network connection on
-#   another interface and will enable IP forwarding if needed, so that the
-#   PXE clients will also have network access.
-# - The Live OS booted via pxelinux is configured with additional boot
-#   parameters:
-#   * nfsroot=${LOCAL_IPADDR}:/mnt/livemedia
-#   * luksvol=
-#   * nop
-#   * hostname=@DISTRO@
-#   * tz=$(cat /etc/timezone)
-#   * locale=${SYSLANG:-"en_US.UTF-8"}
-#   * kbd=${KBD:-"us"}
-#   Which shows that the configuration of the Live OS where the PXE server
-#   runs is largely determining the configuration of the PXE clients.
-# - Note that when networkbooting, the hostname of the Live OS will be
-#   suffixed with the machine's MAC address to make every network-booted
-#   Live OS unique.
