1. Use new dialog menu hacks (no strings, just arrays of dialogMenuItem structs)
so that I can create composite menus with radio/checkbox/... items in them,
removing some long-standing UI bogons in various menus. This work isn't
finished yet, but will be done in two phases. This is phase one.
2. Remove all the script installation stuff. I never got time to document it,
it was arcane and it just complicated much of the code. There are better
ways of doing this if I want to do auto-driven installations later.
3. Remove much dead code and otherwise attempt to remove as much historical
grot as possible so that this code is easier to hack on. This is also
a two-stage process, phase one of which is now complete.
1. Revamp package installer to use new dependency lists and also
pkg_add's new `read from stdin' mode to prevent a copy of the package
from hitting the disk unnecessarily.
2. More fixes for running "not as init" - don't get upset if CDROM already
mounted, do the right thing instead.
3. If running as init, assume first-time install and _don't show the
(W)rite option in the fdisk screen.
4. Many other little tweaks, some of which will have to wait for fuller testing
until I can create a boot floppy (testing certain system-destroying
features of sysinstall can be a royal pain). Expect some more commits.
