2017-05-05tools: relax lint rule for regexpsRich Trott
Relax the rule for maximum line length in JS files if the line contains a regular expression literal. This will avoid the need to convert a regular expression literal into a RegExp constructor call broken across multiple lines in order to satisfy the maximum line length rule. That practice hampers readability.

2017-05-01tools: require function declarationsRich Trott
Except for arrow functions, require function declarations instead of function expressions via linting. This is the predominant style in our code base (77 instances of expressions to 2344 instances of declarations).

2017-04-18tools,lib: enable strict equality lint ruleRich Trott
Enablie a lint rule to require `===` and `!==` instead of `==` and `!=` except in some well-defined cases: * comparing against `null` as a shorthand for also checking for `undefined` * comparing the result of `typeof` * comparing literal values In cases where `==` or `!=` are being used as optimizations, use an ESLint comment to disable the `eqeqeq` rule for that line explicitly. I rather like this because it's a signal that the usage is intentional and not a mistake.
