Forked pssh

Includes a number of improvements, including a --script option and a companion --sudo option

It looks like there are some great features you added, but it's a little
hard to tell what all of the commits are. Would you consider splitting
the changes into individual features and submitting patches? It looks
like you've done some great work, and it would be a shame not to include
them in the official version. Thanks.
