Updating optparse.js to 1.0.3
Updating websocket.js to the December 08, 2011 fork by alaingilbert https://github.com/alaingilbert/node-websocket-client/blob/master/lib/websocket.js
Fix the sys package for v0.5 and v0.6 of nodejs because it was renamed to util. This fix makes it backward compatible with 0.4.
Use /usr/bin/env not /bin/env

Not all platforms have the `env` script located at (or symlinked) at `/bin/env`
but it is fairly standard for all UNIX and UNIX-likes (e.g. Linux distros, BSDs, OS X)
to have it located or symlinked in `/usr/bin/env`.
