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.

/**

|
* Creates an object with the same keys as `object` and values generated by
|
|
* running each own enumerable property of `object` through `iteratee`. The
|

|
* @param {Object} object The object to iterate over.
|
|
* @param {Function|Object|string} [iteratee=_.identity] The function invoked per iteration.
|

* @example
|
|
*
|
|
* var users = {
