More esprima errors

Go through the esprima code and audit all error message it is able to generate. Integrate all that are useful to us.

The mappings for esprima errors live here; the validation tests live here (though check the other language validation tests, which are more robust, for inspiration). The translation file that generates the error messages is here.

从 src/validations/javascript/esprima.js 开始，将其中的错误映射与 src/validations/javascript.js 中的验证测试以及其他语言的验证测试进行比较。查看 locales/en.json 了解生成的消息。当有用的 Esprima 错误已完成映射、翻译并由验证测试覆盖时，即表示完成。
