Added support for using terminfo/termcap instead of curses. By default,
configure chooses to use ncurses if found, of terminfo if only curses was found. --with-terminfo parameter can be used to specify if you want it or not. git-svn-id: http://svn.irssi.org/repos/irssi/trunk@1924 dbcabf3a-b0e7-0310-adc4-f8d773084564
