Title: Enhance Clone to Accomodate Date Objects

Currently `_.clone()` returns an `Object` instead of a `Date`. This push provides a simple and robust fix by creating a `new Date()` and `setTime()` appropriately:

```javascript
if (_.isDate(obj)) return new Date().setTime(obj.getTime());
```

Note a reverted commit with an accidental minification needs squashing.
