Open modules per Gaurav Nelson

OpenShift docs repository uses symlinks for the modules folder. Therefore, when you include modules in your assemblies files, you only have to use module/<file-name>.adoc` instead of the entire path. However, GitHub's default AsciiDoc preview does not honor the symlinks. As a result, when you click the link for modules in GitHub, it shows a 404 error.

When you open any assemblies, this add-on goes through all the included module links and updates the addresses to point to the correct file address for that module.

To use it:

1. Open the assembly file in GitHub.
2. Refresh the page.
3. Links for all modules will update and show a green underline.
4. Click on the update links to open the modules directly in GitHub.
