Make pourover work with lodash (non-underscore build).

Making PourOver work with [Lo-Dash](http://lodash.com/) (non-underscore build) was simply...
 * Replacing the semi-chain syntax to regular syntax.<br>
  In Lo-Dash using `_(...)` is assumed for chaining.
<br><br>
 * Using `_.create` instead of `_.clone`.<br>
  In Underscore a shallow `_.clone` will assign inherited properties of source objects but in Lo-Dash it will only assign own properties of source objects. To work around this we use `_.create`, which is like `Object.create`, when available.
