[CFT] ncurses update

The ncurses in the base system is way too old, say 5.2. Now we
have 5.6 in the portstree. I have a mega patch that update the base
system's ncurses to 5.6. To test it,

cd /usr/src
fetch http://people.freebsd.org/~rafan/ncurses/ncurses-5.6-fbsd7-20070106.diff.gz
mkdir -p lib/ncurses/form lib/ncurses/menu lib/ncurses/ncurses lib/ncurses/panel
zcat ncurses-5.6-fbsd7-20070106.diff.gz | patch -p0

Then, make a new world see if anything if broken. According to the
author, the ABI should be compatible. So, there is no need to recompile
your ports.

The rest information can be found at
