Fix curses library detection. A custom autoconf macro searched for the curses library, and provided an option to use ncurses instead of a (presumably deficient) curses implementation. Unfortunately, some of the Makefiles ignored the search's results. Now that this is fixed, building against pdcurses should be easier too.
