ESLint

Plugin

Uses semistandard. On top of that defines all globals for exposed sketch classes and some other globals available through Cocoascript environment.

Also disables eqeqeq rule, as it is not really feasable in Cocoascript, due to the various different types you are dealing with (NSString == string, but NSString !== string).
