Make "selection bar" inverse video white-on-blue on color screens to avoid
it getting muddled up with popup dialogs.
Do disk selection in a more friendly fashion (for one thing, allow a
drive to be de-selected again if you change your mind).
Add a few strategic screen-saves to prevent corruption of screen contents
(thanks, Michael Elbel!).
I still have a _very very annoying_ display bug which occurs when a menu
item causes a submenu to be displayed - the screen repaints for the original
menu (which is restored upon return from the submenu) are off by about 4
characters. I've tried restoring the screen, the cursor position, you name
it - same deal. Grrrr! This commit is my first step in trying to get someone
else to help me look into this one since I'm just tearing my hair out at this
point!
multi part stuff centralized.
The final check is backwards or something so it always said it failed,
even it it didn't.
Fixed tcpip address check to not be stupid, 10.0.255.1 is legal.
