Fix amd-bower hello-world

- Modify the path to 'globalize' that was causing errors
- Modify README.md to introduce the use of SimpleHTTPServer of Python
The python way is the easiest one I know to start a server. But, I think it's positive to give users other options as well. Like: https://github.com/nodeapps/http-server for node.js. Could you include that? Example

Run `python -m SimpleHTTPServer` to start a server. Other alternatives...

OR

Start a server:
- `python -m SimpleHTTPServer`, or
- Use [http-server](https://github.com/nodeapps/http-server), or
- Install nginx, or
- Install apache,
- Etc :p
