make cli standalone

This makes the fnlfmt executable standalone, so it can be moved or
symlinked to without having to mess with package.path.

The executable here was compiled with a Fennel 0.4.1-dev version with
the recent changes to `include`, which gives more readable output than
older versions.

add support for stdin via `fnlfmt -`

Use body-style for doto.

Rename module to fnlfmt.
