Update JSXTransformer and react-with-addons to 0.11.1

The original JSXTransformer 0.11.0 duplicated the declaration of 'loadScripts' and 'runScripts' which violated the strict mode. It's been fixed in 0.11.1 since https://github.com/facebook/react/commit/067644a4ae51c395c263f29f1b7bfdf791df77aa
Consider my comment :)
