通过同步AJAX请求实现，性能低下，请只用于开发调试，生产环境请使用webpack等静态编译工具。
Implement by Synchronous AJAX, low performance, we use it in development and debug, not use it in production environment.
支持Babel版本: Babel5.x
加载模块时，如果配置了jsx，并且该模块属于jsx项配置的目录下，则加载".jsx"文件，否则加载".js"文件。 Config exmaple:
<script type="text/javascript">
require.config({
jsx: ["app"]
});
</script>
<script type="text/babel">
// 会加载"app/app.jsx"
// Will be load "app/app.jsx"
import App from "app/app";
// 会加载"lib/hello.js"
// Will be load "lib/hello.js"
import Hello from "lib/hello";
