Replaces references to the 'sys' module with 'util'.

[atourino]

This is a simple search / replace job enabling supervisor to work with later node versions. From the changelog, the sys to util renaming occurred with node 0.3 so this patch will probably require node 0.3+ but I haven't tested any node versions before 0.6 which is what I have installed.

I tried out your branch with this npm command

npm install https://github.com/atourino/node-supervisor/tarball/replace_sys_reference_to_util -g

Sadly, this does not seem to work with Node.js 0.6:

If I add -f to the install command, it installs as intended.

You need to fix the supported versions in package.json :)

This aside, supervisor works great on 0.6 with this patch applied.

Thanks for the pointer @mikl!

Thanks! It looks like the package was already not working with node < 0.3.7, so this should be no problem.
