Remove the old hotkeys feature, and replace it by an interactive string
search.
From nconfig help:

Searching: pressing '/' triggers interactive search mode.
           nconfig performs a case insensitive search for the string
           in the menu prompts (no regex support).
           Pressing the up/down keys highlights the previous/next
           matching item. Backspace removes one character from the
           match string. Pressing either '/' again or ESC exits
           search mode. All other keys behave normally.

Miscellaneous other changes (including Rundy's and Justin's input).

This patch was inspired by the kernel projects page, where an ncurses
replacement for menuconfig was mentioned (by Sam Ravnborg).

Building on menuconfig, this patch implements a more modern look
interface using ncurses and ncurses' satellite libraries (menu, panel,
form). The implementation does not depend on lxdialog, which is
currently distributed with the kernel.
