tools: update ESLint to version 2.1.0

Update ESLint to 2.1.0. ESLint has a number of potentially-useful new
features but this change attempts to be minimal in its changes.
However, some things could not be avoided reasonably.

ESLint 2.1.0 found a few lint issues that ESLing 1.x missed with
template strings that did not take advantage of any features of
template strings, and `let` declarations where `const` sufficed.

Additionally, ESLint 2.1.0 removes some granularity around enabling ES6
features. Some features (e.g., spread operator) that had been turned off
in our configuration for ESLint 1.x are now permitted.

+ * This method is like `_.clone` except that it accepts `customizer` which
+ * is invoked to produce the cloned value. If `customizer` returns `undefined`
+ * cloning is handled by the method instead. The `customizer` is invoked with
+ * up to four arguments; (value [, index|key, object, stack]).

+ * @param {*} value The value to clone.
+ * @param {Function} [customizer] The function to customize cloning.
+ * @returns {*} Returns the cloned value.
+ * @example
+ *
+ * function customizer(value) {
+ *   if (_.isElement(value)) {
+ *     return value.cloneNode(false);
+ *   }
+ * }
+ *
+ * var el = _.cloneWith(document.body, customizer);

+ * // => false
