Support ESLint 3.3.1

New rules:

• no-template-curly-in-string: warn if it looks like you're trying to use interpolation in a normal string
• no-unsafe-negation: error if attempting something like if (!thing instanceof Foo) which should probably be if (!(thing instanceof Foo))
• no-global-assign: warn if attempting window = {} or similar
• no-self-assign: new props flag to error if doing a.b = a.b or similar
• func-call-spacing: warn if there is a space between function identifier and invocational parens
• sort-keys: off (would alphabetize keys of objects)
