Coding standards and GPL license in README

First of all: awesome module. I didn't try it yet, but this is an excellent way to prevent linkrot.

Secondly: some remarks.
- Your code doesn't follow the Drupal coding standards. That makes it really hard to review for Drupal developers. You can use coder.module to help you make it "Drupal-compliant".
- You should not add the GPL license to your README. The packaging scripts will automatically add a LICENSE.txt file, in which you'll find the GPL license! :)

Thanks for contributing!
