[CentOS-virt] Updating PXE documentation for CentOS wiki

I was just looking at the CentOS Wiki at
https://wiki.centos.org/HowTos/PXE/PXE_Setup, and it's pretty
seriously out of date. It neglects the existence of the
"syslinux-tftpboot" RPM, and the hand editing of xinetd config files
for tftpd ignores the availability of "chkconfig" and "service" to
manage that service.

For more sophisticated users, it doesn't mention "never, never, never
set your default menu to install an OS by default, because you *will*
accidentally wipe servers that select PXE boot first before local disk
as their boot media". Nor does it mention the difficulties with PXE
and NAT based virtual host, nor how to verify the TFTP service's basic
operation, nor the difficulty of maintaining multiple PXE configs when
the main rsync mirrors only publish the most recent CentOS.

I'm happy to add that sort of thing to the wiki, but I'm finding the
"Set up an account" page confusing. Is "FirstnameLastname" supposed to
be your mandated login name?
