Initialise map of ncurses extended keys.

Determine the keycodes for ncurses extended keys and fill in the KeyNames array.

This function must be called after initscr(), or tigetstr() returns -1. This creates a bit of a chicken-and-egg problem because km_init() is called prior to start_curses(). This means that the default keybindings can't include any of the extended keys because they won't be defined until later.
