[9fans] Standalone *nix port of sam

[Rob King <jking@deadpixi.com>]

Hello everyone,
    I don't know how much interest there'd be, but if anyone ever needs
to run sam standalone on *nix (that is, without plan9port), there's a
standalone version available. It's based on the original port to X11
back in the 80s released by Lucent in 1989 or so.

    There aren't any dependencies other than Xlib/Xft, and it comes with
scalable font support, a much improved B shell command (handles multiple
instances of sam, and even better can be invoked on any machine involved
in a sam -r session, even the remote one), and a few other changes.

    So yeah, it's not sam on Plan 9, but I have to use Linux on my work
machines and can't install plan9port on them, so...there ya go. It
should work on other *nix systems too, but I don't have any to try it
out on. The code isn't pretty; I just hacked on it until I got it
working the way I wanted to, but it's been stable enough for me.

    Please let me know if you have any questions.
