New BSDinstall ISOs

[Nathan Whitehorn]

Following requests from many people, it is now possible to revise setup 
for the new OS after going through the configuration steps and before 
committing and rebooting (this is *almost* a back button). ISOs for i386 
and amd64 that implement this change, as well as several other 
improvements, can be found here:

http://people.freebsd.org/~nwhitehorn/bsdinstall-amd64-20110128.iso.bz2

There is one existing bug that I know about, which is that the services 
menu reflects its defaults when reentered, not the options chosen 
earlier. This will be fixed soon.
