Added another couple of menu item types.
Reshuffled the menus and added a few more. Sure wish I could figure out
how to initialize a menu with _one_ initializer rather than two! :(
more to come in the next 24 hours, this is just the first stable result of
8 hours of hacking so far. The specification format for menus is pretty
much hammered out and the beginnings (very humble) of the doc hierarchy
are present for an example. It should be quite easy to add a lot more
menus quickly to this since I did go somewhat out of my way to make the
framework easy to work with. This is NOT the glorious semi-graphical
sysinstall (or whatever its name will be) that the install-geeks are working
on, this is simply the "son of sysinstall" I've been promising to write in
the interim for 2.0.5 and 2.1R (super install doesn't come until 2.2R).
