Added module documentation visualization and fixed haml top bar

Hello,

in order to have a better visualization of the module in the web page I have added the README.md or README.markdown files included in the own compressed module, and parsed to html using redcarpet library (https://github.com/vmg/redcarpet) to be conveniently shown.

I have also fixed some issues with the top bar, which didn't correctly show the title of the modules.

Best regards,
José Molina Colmenero
