filer dialogs

Can you remove all these and use this in MakeDriveFileSystem.js instead?

```
    var ExtensionUtils = require("utils/ExtensionUtils");
    //css file import
    ExtensionUtils.loadStyleSheet(module, "../../../thirdparty/filer-dialogs/style/style.css");
    ExtensionUtils.loadStyleSheet(module, "../../../thirdparty/filer-dialogs/bower_components/font-awesome/css/font-awesome.min.css");
```
