Addes Bootstrap LESS files

Unfortunately, the docpad-less plugin breaks when using the "@import" directive, so I had to work around that.

I've created a directory /src/style/ with the LESS files, which need to be compiled manually (see README.md) to /src/files/style.css

Also, i've included bootstrap.min.js for Bootstrap's Javascript components.

Although the work-a-round may be clumsy, it only adds functionality to the skeleton, which is why I send this pull request.
