Fixed Genji's problem where .js files were not found through github.

The problem is that Github automatically uses Jekyll, which is basically a parsing software (you can learn more about Jekyll through (here)[http://jekyllrb.com/].

The thing is the Jekyll makes use of files whose names start with an underscore, or _, so the javascript files that started with an underscore cannot be found.

I just removed the underscores from the names of the files and redirected the html's JS src towards the new file names.
