Bug 17869

Because I've been incredibly bored today, continue my minor doc patches.
This time, I've been looking at the installation section. In no
particular order:

 * Minor grammar nits
 * Suggest Partition Magic to users; IMO, this is probably the most
userful utility for those who use multiple OSs.
 * Sysinstall is now much more user-friendly wrt to ppp installation &
setup
 * Sysinstall will setup anonymous FTP for you if you ask it to
 * IDE CDROM Device name change: wcd -> acd
 * Add some more information about downloading the distribution from
ftp.FreeBSD.org
 * The IP address for ftp.FreeBSD.org was incorrect; fix it
 * Windows File Manager -> Windows Explorer (since there are probably 3
people left in the world that still use Win16)
 * Note that IDE drivers are ad* in 4.0 and later
 * Installation types: Novice -> Standard

How-To-Repeat: 
 Become really bored while having a copy of the CVS repository on your
hard drive. :) [Or notice that the handbook does not have any of the
above]
