ecma-runtime-cat 0.3.5

ECMAScript runtime: native built-ins (console, Math, JSON, parseInt, isNaN, Promise, Object, Array, Error, ...) that the boa-cat engine exposes to scripts. v0.3.5 adds the seven standard error constructors `Error`, `TypeError`, `RangeError`, `SyntaxError`, `ReferenceError`, `EvalError`, `URIError`. Each is callable as `Error(message)` or `new Error(message)` and returns an Object with `name` (the constructor's name) and `message` (the first argument coerced via `to_string`).
