Add auto-fill-on-delete. When deleting an 'A'uto created partition

sysinstall will automatically expand the previous partition to take up
the freed up space.  So you can 'D'elete /home and /usr will get the
combined space, or you can 'D'elete /tmp and /var will get the combined space.

This gives the user, developer, or lay person a huge amount of flexibility
in constructing partitions from an 'A'uto base.  It takes only 3 or 4
keystrokes to achieve virtually any combination of having or not having
a /tmp and/or /home after doing an 'A'uto create.

Change 'A'uto creation of /var/tmp to 'A'uto creation /tmp, which should
be less controversial.
