Title: Getting jQuery ready for Node.js 0.5.8+; .isEmptyObject optimization

Node.js is phasing out the 'sys' library, and replacing it with 'util'. Functions are still the same, but there will be a warning message for everything ran through Node.js with anything using 'sys' until it is completely removed.

.isEmptyObject shouldn't need a for() loop, when Object.keys().length will work for arrays and objects.
