some macports updates

if macports is detected:
- check for ncurses from macports
- adjust the library search path to include /opt/local/lib
- adjust the C compiler include search path to include /opt/local/include
  via -I/opt/local/include.
- if libncursesw* is in /opt/local/lib, link with it.

Also, USEMACPORTS=1 will use macports if you have both homebrew and macports.
It isn't required, but the ordering in the Makefile will use homebrew first
otherwise.
