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.
