Add sfeed_curses wrapper which adds a configuration file

It uses a sed script to delete comments, verify, and provide $HOME
substitution, then simply passes each line as an argument to env(1),
which calls sfeed_curses(1).

It also automatically runs it on the feeds in the feed directory
specified by sfeedpath (see sfeedrc(5)) if no arguments are given.
(You must run it on /dev/stdin to read from stdin.)
