Title: removes dependency on `util`

since i'm using node-clone with an ender build, the dependency on `util` throws an error in the browser (rightfully so) since the dependency isn't found.

given that `util` is only included for `isDate`, `isArray`, and `isRegExp` — I decided to inline those methods to get it working.
