A few sysinstall patches I need to get around to testing/committing.  If
they're here, they build cleanly, but that's the only testing I've done.

call-it-a-slice.patch  

	Calls "partitions" slices everywhere, on the assumption that the
	sooner we get the user used to FreeBSD terminology, the better.

unmount-media.patch

	Unmounts the distribution media when exiting sysinstall.  At the
	moment, you get a nice dialog box telling you to remove the CD/DVD,
	from the drive, which probably won't work, because it's mounted 
	(if the CD drive locks the disk).  So just unmount the dist 
	mountpoint first.
