Warn if NcursesW (or similar) is not found

Browse Source 
Add a prominent warning if NcursesW (or some other wide-character version
of Curses) is not found at build time.  It is not an error because the
game might be run under a single-byte encoding (eg, ISO8859-1), even if
compiled under a multibyte encoding (eg, UTF-8).
