Subject: [PATCH 2/3] Support using environment variables as input data

This uses the $_ENV superglobal, which is an empty array unless the
variables_order ini directive contains "E"; see
http://php.net/manual/en/ini.core.php#ini.variables-order.

Environment variables have lower precedence than input data passed via
other means, e.g.

    $ echo '{{USER}}' | twigc --env
    peets
    $ echo '{{USER}}' | twigc --env -p USER=foo
    foo
