Friendlier names for keyboard selection screen
The names of the keyboard layouts specified don't have "friendly" names which might make it more difficult for users to choose the one they want. This is actually a holdover from the Gentoo days - Gentoo's live media just shows the two letter codes, not the full names. It would be great if we could show more friendly names, perhaps leaving the raw names in parenthetical: United States (us)
for instance.
